Study of some local and global axial condensates in QCD at finite temperature
Nicoletta Carabba, Enrico Meggiolaro
The aim of this work is to study some possible local and global axial condensates in the high-temperature chirally restored phase of QCD, by means of two nonperturbative ana…
QCD axion and topological susceptibility in chiral effective Lagrangian models at finite temperature
Salvatore Bottaro, Enrico Meggiolaro
In this work we compute the axion mass and, from this (exploiting a well-known relation), we also derive an expression for the QCD topological susceptibility in the finite-temperat…
Study of the interactions of the axion with mesons and photons using a chiral effective Lagrangian model
Giacomo Landini, Enrico Meggiolaro
We investigate the most interesting decay processes involving axions, photons and the lightest pseudoscalar mesons, making use of a chiral effective Lagrangian model with lig…
Theta dependence of the vacuum energy density in chiral effective Lagrangian models at finite temperature, above
Enrico Meggiolaro
In this work, extending a previous study at zero temperature (), we perform a systematic study of the modifications to the QCD vacuum energy density in the finite-te…
Study of the theta dependence of the vacuum energy density in chiral effective Lagrangian models at zero temperature
Francesco Luciano, Enrico Meggiolaro
We perform a systematic study of the modifications to the QCD vacuum energy density in the zero-temperature case () caused by a small, but non-zero, value of the par…
Gauge-invariant field-strength correlators for QCD in a magnetic background
Massimo D'Elia, Enrico Meggiolaro, Michele Mesiti +1
We consider the properties of the gauge-invariant two-point correlation functions of the gauge-field strengths for QCD in the presence of a magnetic background field. We discuss th…
