Higgs boson decay in the large N limit
John Morales, R. Martinez, Rodolfo A. Diaz +1
The Equivalence Theorem is commonly used to calculate perturbatively amplitudes involving gauge bosons at energy scales higher than gauge boson masses. However, when the scalar sec…

Can large fermion chemical potentials suppress the electroweak phase transition ?
Carlos Quimbay, John Morales, Rafael Hurtado
We calculate the critical temperature ) of the electroweak phase transition in the minimal standard model considering simultaneously temperature () and fermion chemical po…

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…
