The critical line of QCD with four degenerate quarks
P. Cea, L. Cosmai, M. D'Elia +1
We determine the pseudo-critical couplings at imaginary chemical potentials by high-statistics Monte Carlo simulations of QCD with four degenerate quarks at non-zero temperature an…
Chromoelectric flux tubes in QCD
Mario Salvatore Cardaci, Paolo Cea, Leonardo Cosmai +2
We analyze the distribution of the chromoelectric field generated by a static quark-antiquark pair in the SU(3) vacuum and revisit previous results for SU(2). We find that the tran…
Testing the Isotropy of the Universe with Type Ia Supernovae
L. Campanelli, P. Cea, G. L. Fogli +1
We analyze the magnitude-redshift data of type Ia supernovae included in the Union and Union2 compilations in the framework of an anisotropic Bianchi type I cosmological model and…
The phase diagram of QCD with four degenerate quarks
Paolo Cea, Leonardo Cosmai, Massimo D'Elia +1
We revisit the determination of the pseudo-critical line of QCD with four degenerate quarks at non-zero temperature and baryon density by the method of analytic continuation. We de…
On the analytic continuation of the critical line
Paolo Cea, Leonardo Cosmai, Massimo D'Elia +2
We perform a numerical study of the systematic effects involved in the determination of the critical line at real baryon chemical potential by analytic continuation from results ob…
Analytic continuation in QCD-like theories at finite density and finite isospin
P. Cea, L. Cosmai, M. D'Elia +1
The method of analytic continuation is one of the most powerful tools to circumvent the sign problem in lattice QCD. The present study is part of a larger project which, based on t…
