An effective theory for QCD with an axial chemical potential
Alexander A. Andrianov, Vladimir A. Andrianov, Domenec Espriu +1
We consider the low energy realization of QCD in terms of meson fields when an axial chemical potential is present; a situation that may be relevant in heavy ion collisions. We sha…
Implications of local parity breaking in heavy ion collisions
Alexander A. Andrianov, Vladimir A. Andrianov, Domenec Espriu +1
Recent data on dilepton production in heavy ion collisions revealed an abnormal excess in the region of invariant masses below 1 GeV. Our proposal is the creation of a slowly varyi…
Chemical potentials and parity breaking: the Nambu-Jona-Lasinio model
Alexander A. Andrianov, Domenec Espriu, Xumeu Planells
We consider the "two flavour" Nambu--Jona-Lasinio model in the presence of a vector and an axial external chemical potentials and study the phase structure of the model at zero tem…
