Determination of m_s and |V_us| from hadronic tau decays
E. Gamiz, M. Jamin, A. Pich +2
The mass of the strange quark is determined from SU(3)-breaking effects in the tau hadronic width. Compared to previous analyses, the contributions from scalar and pseudoscalar spe…
Leptonic Probes of the Standard Model
A. Pich
Precise measurements of the lepton properties provide stringent tests of the Standard Model structure and accurate determinations of its parameters. We overview the present status…
NNLO tau+tau- production cross section at threshold
P. Ruiz-Femenia, A. Pich
The threshold behaviour of the cross section sigma(e+e- -> tau+tau-) is analysed, taking into account the known higher-order corrections. At present, this observable can be determi…
Vector form factor of the pion : A model-independent approach
A. Pich, J. Portoles
We study a model-independent parameterization of the vector pion form factor that arises from the constraints of analyticity and unitarity. Our description should be suitable up to…
Rho Meson Properties in the Chiral Theory Framework
J. J. Sanz-Cillero, A. Pich
We study the mass, width and couplings of the lightest resonance multiplet with I(J^{PC})=1(1^{--}) quantum numbers. Effective field theories based on chiral symmetry are employed…
The Standard Model of Particle Physics: Status & Low-Energy Tests
Antonio Pich
Precision measurements of low-energy observables provide stringent tests of the Standard Model structure and accurate determinations of its parameters. An overview of the present e…
Colourless Mesons in a Polychromatic World
A. Pich
The limit of a large number of QCD colours gives a useful approximation scheme to the physical hadronic world. A brief overview of the mesonic sector is presented. The large-Nc con…
