Dispersion relations at finite temperature and density for nucleons and pions
Rafael Hurtado, John Morales, Carlos Quimbay
We calculate the nucleonic and pionic dispersion relations at finite temperature T and non-vanishing chemical potentials in the context of an effective chiral theory that d…

Getting bounds on the mixing angles for a non-sequential bottom quark
R. Martinez, J-Alexis Rodriguez, M. Vargas
We analyze the vertex Zff in the framework of models that add a new bottom quark in a nonsequential way and we evaluate the tree level contribution to LEP/SLC data , …

Fermionic dispersion relations at finite temperature and non-vanishing chemical potentials in the minimal standard model
John Morales, Carlos Quimbay, Frank Fonseca
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 fermio…
