Two-flavor QCD at finite quark or isospin density
P. Cea, L. Cosmai, M. D'Elia +2
We exploit analytic continuation to prolongate to the region of real chemical potentials the (pseudo)critical lines of QCD with two degenerate staggered fermions at nonzero tempera…
Comment on the evidence of the Higgs boson at LHC
Paolo Cea
We comment on the Standard Model Higgs boson evidence from LHC. We propose that the new resonance at 125 GeV could be interpreted as a pseudoscalar meson with quantum number $J^{PC…
Chromoelectric flux tubes and coherence length in QCD
Paolo Cea, Leonardo Cosmai, Alessandro Papa
The transverse profile of the chromoelectric flux tubes in SU(2) and SU(3) pure gauge theories is analyzed by a simple variational ansatz using a strict analogy with ordinary super…
Chiral Symmetry Breaking in Planar QED in External Magnetic Fields
Paolo Cea, Leonardo Cosmai, Pietro Giudice +1
We investigate planar quantum electrodynamics (QED) with two degenerate staggered fermions in an external magnetic field on the lattice. We argue that in external magnetic fields t…
The critical line of two-flavor QCD at finite isospin or baryon densities from imaginary chemical potentials
P. Cea, L. Cosmai, M. D'Elia +2
We determine the (pseudo)critical lines of QCD with two degenerate staggered fermions at nonzero temperature and quark or isospin density, in the region of imaginary chemical poten…
