Searching for P- and CP-odd effects in heavy ion collisions
A. A. Andrianov, V. A. Andrianov, D. Espriu +1
In this talk we will summarize the main results from our recent work concerning the possibility that a new metastable phase occurs in some heavy ion collisions (HIC). This phase wo…
Searching for P- and CP- odd effects in heavy ion collisions
Xumeu Planells
In this thesis we study the possibility that QCD breaks parity at high temperatures and densities, a scenario that may be tested in heavy ion collisions. Analytical studies with ef…
Analysis of dilepton angular distributions in a parity breaking medium
Alexander A. Andrianov, Vladimir A. Andrianov, Domenec Espriu +1
We investigate how local parity breaking (LPB) due to large topological fluctuations may affect hadron physics. A distorted dispersion relation is derived for the lightest vector m…
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…
