Rare top quark decays in extended models
R. Gaitan, O. G. Miranda, L. G. Cabral-Rosetti
Flavor changing neutral currents (FCNC) decays t to H + c, t to Z + c, and H to t + bar{c} are discussed in the context of Alternative Left-Right symmetric Models (ALRM) with extra…
Rare top quark and Higgs boson decays in Alternative Left-Right Symmetric Models
R. Gaitan, O. G. Miranda, L. G. Cabral-Rosetti
Top quark and Higgs boson decays induced by flavor-changing neutra currents (FCNC) are very much suppressed in the Standard Model (SM). Their detection in colliders like the Large…
A New Method to Infere Which Type of Neutralinos Make Up Galactic Halos
Luis G. Cabral-Rosetti, Xavier Hernández, Roberto A. Sussman
Applying the microcanonical definition of entropy to a weakly interacting and self--gravitating neutralino gas, we evaluate the change in the local entropy per particle of this gas…
Magnus Expansion and Three-Neutrino Oscillations in Matter
Alexis A. Aguilar-Arevalo, L. G. Cabral-Rosetti, J. C. D'Olivo
We present a semi-analytical derivation of the survival probability of solar neutrinos in the three generation scheme, based on the Magnus approximation of the evolution operator o…
Neutrinos and Nucleosynthesis in Supernova
U. Solis, J. C. D'Olivo, L. G. Cabral-Rosetti
The type II supernova is considered as a candidate site for the production of heavy elements. The nucleosynthesis occurs in an intense neutrino flux, we calculate the electron frac…
One-Loop Electroweak Corrections to the Muon Anomalous Magnetic Moment Using the Pinch Technique
L. G. Cabral-Rosetti, G. López Castro, J. Pestieau
The definition of the physical properties of particles in perturbative gauge theories must satisfy gauge invariance as a requisite. The Pinch Technique provides a framework to defi…
