Lorentz-symmetry violating decays in a medium
José F. Nieves, Palash B. Pal
Various decay processes, such as the decay of a spin-1 particle into two photons or the gravitational decay of a spin-1/2 fermion, are forbidden in the vacuum by a combination of r…
Neutrino induced threshold production of two pions and N^*(1440) electroweak form factors
E. Hernandez, J. Nieves, S. K. Singh +2
We study the threshold production of two pions induced by neutrinos in nucleon targets. The contribution of nucleon, pion and contact terms are calculated using a chiral Lagrangian…
Photogravitational processes
Jose F. Nieves, Palash B. Pal
In the linearized theory of gravity coupled to the electromagnetic field, we calculate the cross sections of two processes in which both the gravitational and electromagnetic inter…
QED at Finite Temperature in the Coulomb Gauge
J. C. D'Olivo, J. F. Nieves, M. Torres +1
We argue that calculations in QED at finite temperature are more conveniently carried out in the Coulomb gauge, in which only the physical photon degrees of freedom play a rol and…
