Structure-dependent radiative corrections to phi -> K^+K^-/K_LK_S decays
F. V. Flores-Baez, G. Lopez Castro
Current predictions for the ratio of phi -> K^+K^-/K_LK_S decay rates exceed the corresponding experimental value in about five standard deviations. By far, the dominant sources of…
CKM-suppressed top quark decays t -> q + W in the SM and beyond
J. L. Diaz-Cruz, R. Gaitan-Lozano, G. Lopez-Castro +1
Top quark decays are of particular interest as a mean to test the standard model (SM) predictions, both for dominant (t -> b + W) and rare decays (t -> q + W, cV, cVV, c phi^{0}, b…
(ω, ϕ) P^- decays of tau leptons
A. Flores-Tlalpa, G. Lopez Castro
The τ-> (ω, ϕ)P^-νdecays, where P^-=π^-, K^-, are considered within a phenomenological model with dominance of meson intermediate states. We assume SU(3) flavor symmetry to fix som…
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…
The width difference of rho vector mesons
F. V. Flores-Baez, G. Lopez Castro, G. Toledo Sanchez
We compute the difference in decay widths of charged and neutral ρ(770) vector mesons. The isospin breaking arising from mass differences of neutral and charged πand ρmesons, radia…
Is there a paradox in CP asymmetries of tau to K_{L,S} pi nu decays?
G. Calderon, D. Delepine, G. Lopez Castro
Based on the description of unstable particles in quantum field theory (QFT), we compute the time-dependent probabilities for transitions between asymptotic states in $τ^…
