Fermionic dispersion relations at finite temperature and non-vanishing chemical potentials in the minimal standard model
We calculate the fermionic dispersion relations in the minimal standard model at finite temperature in presence of non-vanishing chemical potentials due to the CP-asymmetric fermionic background. The dispersion relations are calculated for a vacuum expectation value of the Higgs field equal to zero (unbroken electroweak symmetry). The calculation is performed in the real time formalism of the t...
متن کاملUniversality in Fermionic Field Theries at Finite Temperature
Phase transitions in QCD at nonzero temperature have been studied intensively over the last decade. However, since the problem of chiral symmetry breaking and its restoration is intrinsically non-perturbative, the number of available techniques is limited and most of our knowledge about this phenomenon comes from lattice simulations. Although there is little disagreement that the chiral phase t...
متن کاملDispersion relations at finite temperature and density for nucleons and pions
We calculate the nucleonic and pionic dispersion relations at finite temperature (T ) and non-vanishing chemical potentials (μf ) in the context of an effective chiral theory that describes the strong and electromagnetic interactions for nucleons and pions. The dispersion relations are calculated in the broken chiral symmetry phase, where the nucleons are massive and pions are taken as massless...
متن کاملDensity effects on the pion dispersion relation at finite temperature
We study the behavior of the pion dispersion relation in a pion medium at finite density and temperature, introducing a chemical potential to describe the finite pion number density. Such description is particularly important during the hadronic phase of a relativistic heavy-ion collision, between chemical and thermal freeze-out, where the pion number changing processes, driven by the strong in...
متن کاملSpontaneous CP Violation in the Minimal Supersymmetric Standard Model at Finite Temperature
We show that in the Minimal Supersymmetric Standard Model one–loop effects at finite temperature may lead to a spontaneous breaking of CP in-variance in the scalar sector. Requiring that the breaking takes place at the critical temperature for the electroweak phase transition, we find that 1
