Chiral symmetry restoration and the thermal state
Andrea Vioque-Rodríguez, Angel Gómez Nicola
We analize the role played by the thermal state or in chiral symmetry restoration. The temperature corrections to the spectral properties of that state are included…
Chiral perturbation theory for nonzero chiral imbalance
Domènec Espriu, Angel Gómez Nicola, Andrea Vioque-Rodríguez
We construct the most general low-energy effective lagrangian including local parity violating terms parametrized by an axial chemical potential or chiral imbalance , up to ${…
Patterns and partners within the QCD phase diagram including strangeness
Angel Gómez Nicola, Jacobo Ruiz de Elvira, Andrea Vioque-Rodríguez
We review the current situation of the pattern of chiral symmetry restoration. In particular, we analyze partner degeneration for and symmetries within the context…
The QCD topological charge and its thermal dependence: the role of the
Angel Gómez Nicola, Jacobo Ruiz De Elvira, Andrea Vioque-Rodríguez
We analyze the contribution of the meson in the first two non-trivial moments of the QCD topological charge distribution, namely, the topological susceptibility and the f…
The role of the thermal or sigma in chiral symmetry restoration
A. Vioque-Rodríguez, A. Gómez Nicola
We analyze the state generated as a pole of scattering within unitarized low-energy effective theories at finite temperature. First, we report on the self-energ…
Chiral and restoration: Ward Identities and effective theories
A. Gómez Nicola, J. Ruiz de Elvira, A. Vioque-Rodríguez +1
We discuss our recent results regarding chiral and restoration, both from the formal point of view of QCD Ward Identities (WI) and from an Effective Theory analysis provid…
