The Gradient Flow Coupling in Technicolor Models

Abstract: Lately, lattice field theory has been used to extensively study technicolor models, a class of candidate models for beyond the Standard Model dynamics. These models should lie close to the lower limit of the conformal window, where the running coupling acquires a nonzero asymptotic value at small energy scales. So far, the most common method for studying the running coupling on the lattice has been the Schrödinger Functional method. I present a study using a novel, Gradient Flow coupling measurement and compare it to the Schrödinger Functional in one prominent technicolor candidate model, the SU(2) gauge theory coupled to 2 fermions in its adjoint representation.

Colloquium: Black hole thermodynamics – then and now

Abstract: Black hole thermodynamics was developed about 40 years ago in the wake of deepening the understanding of the black hole phenomenon. It has remained lively by ramifying into a few subjects which are active fields of research today. I will describe, from a personal point of view, how the subject started and show how it connects to some contemporary issues in theoretical physics.

Workshop on Cosmology

Cosmological perturbations post-Planck, workshop on the impact of Planck
satellite and other recent data on the study of cosmological
perturbations, 4-7 June, 2013, Helsinki, Finland. Location: seminar room

the disposal of the participants.
 
Big Data Seminar Invitation
—————————–
The seminar “Big data, great science, small Finland: Our role in Global
Research Data Exchange” will be arranged in Kumpula on the 4th of June
2013 during the time 12-16.
 
Modern scientific developments require large infrastructures and they
generate enormous amounts of research data. The problems of Big Science
and Big Data need international viewpoints and common practices for
solution. The recent launch of the Research Data Alliance (RDA) brought
to the surface many new opportunities for global collaboration in the
field of research data.
 
There is clearly now a need in Finland to continue the discussion
between the researchers, e-Infrastructure providers and funding bodies,
which has already started during the TTA process.
 
The aim of this meeting is to initiate discussion on the development of
big science and big research in Finland and find the ways how we can
interact with the international community and position ourselves in
respect to the recent and future developments on research data
challenges, such as building interoperable research data systems and
research data exchange.
 
We kindly invite you to the event on the 4th June from 12:00 to 16:00,
room CK112, in Exactum at Kumpula Campus, Helsinki.

The effects of Dirac low-mode truncation on the hadron mass spectrum in lattice QCD

Abstract: Chiral symmetry breaking in Quantum Chromodynamics is associated with the low lying spectral modes of the Dirac operator according to the Banks-Casher relation. We investigate how removal of a variable number of low lying modes from the valence quark sector affects the masses of the ground states and first excited states of baryons and mesons in two flavor lattice QCD.

Finite density QCD from an effective lattice theory

Abstract: QCD at finite baryon density is not amenable to Monte Carlo simulations because of the notorious Sign Problem. Apprxomiate methods to circumvent it have been developed but are restricted to small chemical potentials. Recently a new strategy utilising an effective theory has been presented, which is derived analytically from lattice QCD by combined strong coupling and hopping expansions. So far the effective theory is valid for heavy quarks only. However, its sign problem is mild and can be solved by complex Langevin methods. The deconfinement transition can be computed for all chemical potentials. Moreover, for the first time the transition to cold nuclear matter has been calculated from QCD directly.

When does the gluon reggeize

Abstract: I will discuss a novel class of Wilson line operators that are supported on a natural ‘completion’ of light cones. By a simple conformal transformation, these operators are shown to govern the high-energy limit of scattering amplitudes (Regge limit), in any CFT or near-CFT such as QCD in the ultraviolet, and their anomalous dimension is the BFKL kernel. In the talk I’ll use these operators to answer some basic questions regarding the structure of the Regge limit — for example, when do gluon-exchange amplitudes exhibit pure power-law energy dependence (Regge pole behavior)?

Pulling oneself over the fence: a bootstrap for quantum gravity

Abstract: Asymptotic freedom is a key ingredient in the successful construction of the Standard Model. It has been conjectured long ago that metric quantum gravity may as well fit into the picture – despite its notorious perturbative non-renormalisability – provided that the theory turns out to be asymptotically safe. We recall the underlying ideas and challenges, and contrast asymptotic freedom with asymptotic safety. We also propose a self-consistent search strategy for the latter and show new results for a simplified version of quantum gravity. Implications for the asymptotic safety conjecture are discussed.
