Spacetime curvature and the Higgs stability before and after inflation

Abstract: The best fit values for the SM parameters imply that the potential for the Higgs boson developes a Planck-scale vacuum with negative energy, which may result in decay of the current vacuum state. In this talk we show the significance of backreaction from classical gravity for vacuum stability in the early universe. After introducing the topic of inflationary vacuum stability, we will concentrate on the non-perturbative effects during reheating and show that they may induce vacuum decay for large inflationary scales. In particular, we conclude that inflation and reheating constrain the non-minimal coupling between the SM Higgs and gravity to be close to 1/6. arXiv:1407.3141 and arXiv:1506.04065.

Searching for cosmological magnetic fields in the diffuse gamma-ray background

Abstract: Several CP violating processes occurring in the early universe could have produced weak-field helical magnetic seed fields that would have subsequently grown, amplified via different types of dynamo mechanism, accounting for the presently observed astronomical-sized fields. The structure of these large-scale magnetic fields is imprinted on the gamma-ray sky through secondary cascades. Using data from the Fermi satellite we evaluate a CP odd statistic and find it to be non-zero above the $2 \sigma$ level. This results indicate a left-handed helical magnetic field of $10^{-14}G$ on $~10$ Mpc scales.

What Next on Axion-like Particles: Current Bounds and Discovery Opportunities

Abstract: Very light axion-like particles (ALPs) with a two-photon vertex are predicted in many extensions of the Standard Model of particle physics. Depending on the actual value of their mass, ALPs can play an important role in cosmology, being valuable dark matter candidates. The coupling with photons allows for ALP-photon mixing in external electromagnetic fields. This effect is exploited for direct searches of ALPs in laboratory experiments. The two-photon vertex would also induce the mixing with ALPs for photons emitted by distant astrophysical sources, and propagating in the large-scale cosmic magnetic fields. This mixing could produce signatures in astrophysical observations, ranging from the cosmic microwave background to the high-energy gamma-rays. In this talk I will present an overview of current bounds on ALPs and discovery opportunities in the planned laboratory and astrophysical experiments.

Real-time phenomena in finite-temperature QCD

Abstract: I present two topics in finite-temperature QCD: one concerns the pion quasiparticle and its dispersion relation in the low-temperature phase; the second concerns non-static screening masses in the high-temperature phase, the corresponding perturbative predictions and the relation of these masses to transport properties and the dilepton rate.

Ward identities and transport in 2+1 dimensions

Abstract: The Hall viscosity of chiral superfluids is determined by the angular momentum density. One can understand and generalize this relation using Ward identities of the energy-momentum tensor. Furthermore, the same identities connect viscosities and conductivities. A preliminary analysis in AdS/CFT reveals that the identities seem to be non-trivial in the sense that they cannot be derived simply from the asymptotic expansion of the solutions.

Looking for hidden supersymmetry

Abstract: After a brief review of the state of supersymmetry after RUN I of the LHC, it will be argued that the supersymmetric electroweak sector may play the leading role in its discovery. Experimental signatures of electroweakinos and the prospects for their discovery will be discussed.
