Neutrino physics: status and quests for the future

Abstract: Neutrino physics has entered the precision era. Nevertheless many questions still remain without an answer. We know that the SM cannot be the ultimate theory, since a so-called “elusive” sector is completely missing: neutrinos are not properly included since we cannot describe their mass. Moroever, the nature, Dirac or Majorana, of the three light active neutrinos nuj (j = 1,2,3) with definite mass mj is unknown. I will review unknown properties of neutrinos and how possibly detect some of them. In particular I will define a theoretical framework and deduce the conditions under which multi-messenger astronomy can constrain neutrino masses and unveil their ordering. The framework uses time differences between the arrival of neutrinos and the other two light messengers, i.e. light and gravitational waves, emitted by astrophysical catastrophes.

Cosmology and the Dark Energy Survey

Abstract: The Dark Energy Survey (DES) is a 5000 square degree survey targeting dark matter and dark energy science. This year sees the release of the first science results from the DES collaboration using data taken during science verification. I plan to present these new results, which include dark matter maps, cosmology constraints and new discoveries such as the new strong lens systems being found. I will also give an update on the progress of the main science survey, which is still ongoing.

Statistical Issues in Searches for New Physics

Abstract: Given the cost, both financial and even more importantly in terms of human effort, in building High Energy Physics accelerators and detectors and running them, it is important to use good statistical techniques in analysing data. This talk covers some of the statistical issues that arise in searches for New Physics. They include topics such as: Blind Analysis. How should we deal with the `Look Elsewhere Effect’? Should we insist on the 5 sigma criterion for discovery claims? Significance P(A|B) is not the same as P(B|A). The meaning of p-values. What is Wilks’ Theorem and when does it not apply? Dealing with systematics such as background parametrisation. Coverage: What is it and does my method have the correct coverage? Upper Limits. The use of p_0 vs p_1 plots. Higgs search: Discovery and Spin.

Relating the Axion Mass and Dark Matter Density

Abstract: QCD appears to allow for large parity and time-reversal violating effects, which are in fact unmeasurably small. The simplest dynamical model to explain this predicts a new particle, the Axion, which is also an excellent dark matter candidate. Under reasonable assumptions it should be possible to predict the relation between the axion’s mass and its dark matter abundance. I will discuss the interesting physics we need to make this prediction concrete — axionic string networks and topological susceptibility.

Nonequilibrium QFT approach to leptogenesis
Abstract: he observed baryon asymmetry of the Universe may have been produced dynamically in the very early Universe by a baryogenesis via leptogenesis process from the CP- and lepton number violating decays of heavy right-handed neutrinos. For reliable calculations of the baryon asymmetry generated in leptogenesis first principle methods of nonequilibrium quantum field theory are required.

We construct a transport theory of leptogenesis based on the Schwinger-Keldysh or Closed Time Path (CTP) formalism of nonequilibrium QFT. The resulting kinetic equations incorporate finite density medium effects and quantum coherence effects and therefore provide a generalization to standard (quantum) Boltzmann equations. We find that the finite density corrections from loop integrals typically lead to an enhancement of the asymmetry. In the resonant regime with nearly degenerate right-handed neutrino masses, our results confirm the well-known resonant enhancement of CP-violation, however, novel effects from the flavour oscillations can be important in the dynamics.

Exclusive processes with TOTEM and CT-PPS: results, perspectives and experimental challenges

Abstract: The latest results and the physics potential of the TOTEM experiment at the LHC will be presented. This include searches for glueballs and new physics together with CMS and a deeper understanding of elastic scattering. For LHC RUN-2, a joint CMS-TOTEM project (CT-PPS) has been approved to study exclusive particle production at the highest LHC luminosity. With the recent indication by the CMS and ATLAS experiments of a possible resonance in the 750 GeV mass region, the CT-PPS, initially designed to search for anomalous gauge boson quartic couplings, will give a relevant contribution in a possible confirmation and study of this new resonance. I will review the CT-PPS status and plans for 2016 LHC running.

In the second part of the seminar I will concentrate on the new detectors designed to precisely measure the time-of-flight of the scattered protons produced in such exclusive processes at medium and high luminosity to be able to reject pile-up. Timing detectors based on diamond sensors have been developed by TOTEM and will be used in the first phase of the CT-PPS project. I will summarize the detector development, performance and perspective for this promising technology.

Efficient calculation of cosmological neutrino clustering

Abstract: Within the next few years cosmological structure formation will be probed in greater detail than ever before by new and very large surveys, most notably EUCLID and LSST. While this opens great possibilities for probing for example dark energy and the mass of neutrinos, it also puts very stringent requirements on theoretical calculations of cosmological observables, such as the matter power spectrum. In this regard, the treatment of massive neutrino is particularly challenging both in N-body simulations and in linear theory Boltzmann codes. In this talk I will present a new approximation to the third moment of the Boltzmann hierarchy and demonstrate that with this new approximation the neutrino power spectrum can be calculated with a precision of a few percent. Then I will discuss an extremely efficient way of calculating the neutrino power spectrum in the regime of non-linear dark matter clustering.

On Higgs physics in the early universe

Abstract: I discuss the role of the Higgs field in the very early universe. Inflationary fluctuations of the Higgs field generically form a primordial Higgs condensate which might have left observable signatures. Stability of the SM vacuum against the fluctuations implies stringent constraints on Higgs couplings to spacetime curvature, or requires physics beyond SM. I review the stability constraints which may open interesting insights in probing new physics. I also discuss the decay of the primordial Higgs condensate which determines the duration of the early out-of-equilibrium epoch. If time allows, I comment also on the observational signatures of Higgs inflation.

Simplified models for DM searches at the LHC

Abstract: As the first results from Run II of the LHC are released, it is important to evaluate the ways in which we study DM at colliders. In the past we have used EFTs to constrain DM in a semi-model-independent way, but it is now clear that this approach has limitations. The community is moving full-speed into the usage of simplified models of dark matter, and it is important to approach them in a logical and consistent way so that we can learn as much as possible about the dark sector. Simplified models are designed to have fewer parameters than full, UV-complete models of dark matter, so that the full parameter space can be explored. At the same time, they are designed to still provide much the same phenomenology as full models, so that we don’t miss any potential signals. I will talk about some of the techniques and challenges we use to achieve these sometimes contradictory goals, and also how collider constraints fit into the broader search for dark matter.

Lattice Model of Ideal Walking

Abstract: We present preliminary studies of the SU(2) gauged NJL model with 2 flavors of fermions in the adjoint representation. The gauge model is infrared conformal and an additional NJL-type four fermion interaction, at large coupling, induces a chirally broken phase. In the symmetric phase the four fermion interaction is expected to influence the dynamics of the infrared fixed point and there may be a second order transition to the chirally broken phase. We study chiral symmetry breaking and the mass anomalous dimension at the infrared fixed point using the mode number of the Dirac operator.

Gravitational reheating after multi-field inflation

Abstract: It has recently been highlighted that details of the reheating process must be properly taken into account when constraining individual models of inflation with current high-precision CMB data, even in the case of single-field models. As inflation models with a non-minimal coupling between the gravity and inflaton sectors have recently attracted much attention, in this work we discuss reheating in this class of models, allowing for multiple inflaton fields. In such models, even in the absence of explicit interaction terms the inflaton sector can decay into matter as a result of its non-minimal coupling to gravity, thereby reheating the Universe gravitationally. Using the Bogoliubov approach we evaluate the gravitational decay rates of the inflaton sector, and analyse the reheating dynamics.

Dark Matter in multi-inert doublet models

Abstract: Dark Matter (DM), arising from an Inert Higgs Doublet, may either be light, below the W mass, or heavy, above about 525 GeV. While the light region may soon be excluded, the heavy region is known to be very difficult to probe with either Direct Detection (DD) experiments or the Large Hadron Collider (LHC). In this talk I will discuss that adding a second Inert Higgs Doublet helps to make the heavy DM region accessible to both DD and the LHC, by either increasing its couplings to the observed Higgs boson, or lowering its mass to 360 GeV < $m_{DM}$, or both.

Top-quark production at the LHC: Theory status and perspectives

Abstract: The current state of precision predictions for top-quark
production at the LHC will be reviewed. Special emphasis will be put on
the definition and the determination of the top-quark mass as a
fundamental parameter of the Standard Model. We will motivate, why
precision determinations of the top-quark mass are important in the
current high-energy run of the LHC and discuss the prerequisites in
theory for the extraction of a well-defined mass parameter in a given
renormalization scheme. We also discuss the implications for the
stability of the Higgs potential and the electroweak vacuum.

Massive neutrino signatures on the large-scale structure of the Universe

Abstract: Neutrinos are described as fundamental particles by the
standard model of particle physics. The fact that neutrinos are massive,
as demonstrated by neutrino oscillations experiments, point towards
physics beyond the standard model. One of the most important questions
in modern physics is: what are the neutrino masses? Current tightest
constrain on the sum of the neutrino masses arise from cosmological
observables. In order to extract the maximum information from current
and future surveys, as well as to avoid introducing biases in the values
of the cosmological parameters, it is of primordial importance to
understand, both at the linear and at the fully non-linear order, the
impact that massive neutrinos induce on the distribution of matter,
halos and galaxies. In this seminar I will present some of the effects
neutrinos induce on the Universe large-scale structure, among then the
clustering of matter, the clustering of dark matter halos, the abundance
of halos, the abundance of voids, their impact on the BAO peak and their
effects on the spatial distribution of neutral hydrogen in the
post-reionization era.

Tying Quantum Knots

Abstract: Knots are familiar entities that appear at a captivating nexus of art, technology, mathematics and science. Following a long period of theoretical investigation and development, they have recently attracted great experimental interest in classical contexts ranging from knotted DNA and nanostructures to vortex knots in fluids. In our work, we demonstrate the controlled creation and detection of knot solitons in the quantum-mechanical order parameter of a spinor Bose-Einstein condensate. Images of the superfluid reveal the circular shape of the soliton core and its associated linked rings. Our observations of the knot soliton establish an experimental foundation for future studies of their stability, dynamics and applications within quantum systems.

SUSY-phenomenology-based models of Higgs inflation

Abstract: Present CMB observation tightly constrains the amplitude of

well-motivated and observationally viable models of inflation, I
discuss supersymmetric Higgs inflation type scenarios in this talk.
These are natural beyond-the-Standard Model extension of the popular
nonminimally coupled Higgs inflation model by Bezrukov-Shaposhnikov. In
this talk I will mainly focus on a scenario based on the supersymmetric
seesaw model.
