tau -> (3 pions) nu_tau : Theory versus Experiment
D. Gomez Dumm, A. Pich, J. Portoles
We analyse tau -> (3 pions) nu_tau decays within the framework of the resonance chiral theory of QCD. We have worked out the relevant Lagrangian that describes the axial-vector cur…
tau -> (3 pions) nu_tau decays in the Resonance Effective Theory
D. Gomez Dumm, A. Pich, J. Portoles
tau -> (3 pions) nu_tau decays are analysed within the framework of the resonance effective theory of QCD. We work out the relevant Lagrangian that describes the axial-vector curre…
Rho Meson Properties
J. J. Sanz-Cillero, A. Pich
We study the mass, width and couplings of the lightest vector multiplet. Effective field theories based on chiral symmetry and a 1/N_C counting are adopted in order to describe the…
Isospin Breaking in K -> Pi Pi Decays
V. Cirigliano, G. Ecker, H. Neufeld +1
We perform a complete analysis of isospin breaking in K -> Pi Pi amplitudes in chiral perturbation theory, including both strong isospin violation and electromagnetic corrections t…
Phenomenology of the <VVP> Green's function within the Resonance Chiral Theory
P. D. Ruiz-Femenia, A. Pich, J. Portoles
We analyse the odd-intrinsic-parity effective Lagrangian of QCD valid for processes involving one pseudoscalar with two vector mesons described in terms of antisymmetric tensor fie…
Isospin violation in epsilon'
V. Cirigliano, A. Pich, G. Ecker +1
On the basis of a next-to-leading-order calculation in chiral perturbation theory, the first complete analysis of isospin breaking for direct CP violation in K^0 -> 2 pi decays is…
