Basics of Resonance Chiral Theory
J. Portoles
We review the main components that have to be considered, within Resonance Chiral Theory, in the study of processes whose dynamics is dominated by hadron resonances. We show its ap…
LFV in semileptonic decays and conversion in nuclei in SUSY-seesaw
E. Arganda, M. J. Herrero, J. Portoles +2
Here we review the main results of LFV in the semileptonic tau decays (), (), and $τ\to μV…
What can be learned from the Belle spectrum for the decay tau- -> nu_tau K_S pi-
Matthias Jamin, Antonio Pich, Jorge Portoles
A theoretical description of the differential decay spectrum for the decay tau- -> nu_tau K_S pi-, which is based on the contributing K pi vector and scalar form factors F_+^{K pi}…
Form Factors in the radiative pion decay
V. Mateu, J. Portoles
We perform an analysis of the form factors that rule the structure-dependent amplitude in the radiative pion decay. The resonance contributions to pion -> e nu_e gamma decays are c…
Analytical approaches to the calculation of f+(0)
J. Portoles
Kl3 decays constitute, at present, the golden modes to extract |Vus| from experimental data. Its incertitude is dominated by the theoretical error in the determination of the vecto…
Vanishing chiral couplings in the large-N_C resonance theory
Jorge Portoles, Ignasi Rosell, Pedro Ruiz-Femenia
The construction of a resonance theory involving hadrons requires implementing the information from higher scales into the couplings of the effective Lagrangian. We consider the la…
