LNGS: S. CARIGNANO - POWER CORRECTIONS TO THE HTL EFFECTIVE LAGRANGIAN OF QED 
 ELENCO COMPLETO 

DATA: 12-11-2018

LABORATORI NAZIONALI DEL GRAN SASSO
I will discuss some recent computations in thermal field theory centered around the Hard Thermal Loop/ Hard Dense Loop formalism. First, I will focus on the derivation of power corrections to the HTL effective Lagrangian and introduce the On-Shell effective field theory (OSEFT) as a tool to systematically derive these contributions. I will then show how the OSEFT Lagrangian can be used to derive the equations of relativistic chiral kinetic theory. Finally, I will show results for the damping rate of a fermion in a chirally imbalanced system and discuss the fate of the chiral instability at vanishing temperature. --- Stefano Carignano Departament de Fisica Quantica i Astrofisica Universitat de Barcelona
