Patterns and partners within the QCD phase diagram including strangeness

High Energy Physics - Phenomenology 2019-10-23 v1

Abstract

We review the current situation of the pattern of chiral symmetry restoration. In particular, we analyze partner degeneration for O(4)O(4) and U(1)AU(1)_A symmetries within the context of Ward Identities and Effective Theories. The application of Ward Identities to the thermal scaling of screening masses is also discussed. We present relevant observables for which an Effective Theory description in terms of Chiral Perturbation Theory and its unitarized extension are compatible with lattice data even around the transition region. We pay special attention to the role of strangeness in this context.
