The quasielastic charged current (CCQE) νen→e⎯pνen→e−p scattering is the dominant mechanism to detect appearance of a νe in an almost νμ flux at the 1 GeV scale. Actual experiments show a precision below 1% and between ...

We review the consistency between the recently proposed spin-3/2 gauge interaction for Δ resonance with nucleons (N) and pions (π), and the fundamental electromagnetic gauge invariance in any radiative amplitude. We show ...

Neutral Yukawa’s model for the description of the interaction between nucleons and pions is studied in the framework of causal perturbation theory, an axiomatic S-matrix quantum field theory in which ultra-violet divergences ...

It is a well known fact that when a resonance (R) is produced and decays, its unperturbed propagator will be singular at p2 mR = 2 when it appears in an s-type Feynman pole graph. Nevertheless this is not a problem, since ...

Esta tesis tuvo como objetivo identificar posibles efectos cuántico-gravitacionales al estudiar sistemas astrofísicos, en el contexto de un marco teórico estructurado idealizado para someter al escrutinio de la naturaleza ...
