K pi vector form factor, dispersive constraints and tau -> nu_tau K pi decays
Diogo R. Boito, Rafel Escribano, Matthias Jamin
Recent experimental data for the differential decay distribution of the decay by the Belle collaboration are described by a theoretical model which is composed of…
alpha_s and the tau hadronic width: fixed-order, contour-improved and higher-order perturbation theory
Martin Beneke, Matthias Jamin
The determination of from hadronic decays is revisited, with a special emphasis on the question of higher-order perturbative corrections and different possibilities of re…
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}…
OPE-RchiT matching at order alpha_s: hard gluonic corrections to three-point Green functions
Matthias Jamin, Vicent Mateu
In this work we push the matching between the QCD operator product expansion (OPE) and resonance chiral theory (RchiT) to order alpha_s. To this end we compute two- and three-point…
