Resummed QCD thermodynamics at finite temperature and chemical potential

Abstract: The thermodynamics of QCD at finite temperature and density is of great interest for the heavy ion collision experiments. In this talk I will discuss about the various thermodynamic quantities calculated within Hard thermal Loop approximation at finite temperature and finite chemical potential. I will also discuss about the possible extensions of the current results to make it more reliable in heavy-ion collision experiments.

Dusty inflation in Born-Infeldized gravity.

Abstract: In order to regularize the energy of point-like charged particles, Born and Infeld introduced a modification of the Maxwell Lagrangian that naturally imposes an upper bound on electromagnetic fields. Similar ideas can be applied to gravity to resolve the GR singularities. I will discuss a class of theories based on this scheme and present a scenario where inflation can be supported by a dust component within the context of these theories.

Towards higher order accuracy in LCPT

Abstract: Hamiltonian perturbation theory in the light cone form (LCPT) has become a standard tool in understanding hadronic scattering processes within a first principles QCD approach. The calculational inconvenience of LCPT compared to standard covariant perturbation theory is balanced by several features that make its physical interpretation more transparent. Due to the more complicated mathematical structure resulting from the breaking of explicit rotational symmetry, LCPT has never been the formulation of choice for higher order loop calculations. More recently, however, calculations of small-x dilute-dense scattering processes in the Color Glass Condensate (CGC) picture have been approaching the NLO level, for example in the small-x evolution equation and inclusive deep inelastic scattering cross sections. In this talk I will discuss our latest work (T. Lappi, R. Paatelainen arXiv:1611.00497), in which we formulate the LCPT rules in helicity space, independently of the spinor representation. This presents a major technological improvement for loop calculations by replacing the Dirac algebra by simple helicity sums. I also demonstrate how to apply this framework to other LCPT calculations.
