hyperon semileptonic decays
C. Barbero, Ling-Fong Li, G. Lopez Castro +1
We compute the rates of semileptonic B_A \to B_Bl^-l^- (l=e or μ) hyperon transitions in a model where intermediate states involve loops of baryons and a Majorana neutrino. These r…

Unstable particles, gauge invariance and the Delta^{++} resonance parameters
G. Lopez Castro, A. Mariano
The elastic and radiative pion(+)-proton scattering are studied in the framework of an effective Lagrangian model for the Delta^{++} resonance and its interactions. The finite widt…
