Global fit to transitions
Clara Murgui, Ana Peñuelas, Martin Jung +1
We perform a general model-independent analysis of transitions, including measurements of , , their differential distribu…
tau -> pi pi pi nu_tau decays and the a_1(1260) off-shell width revisited
D. Gomez Dumm, P. Roig, A. Pich +1
The tau -> pi pi pi nu_tau decay is driven by the hadronization of the axial-vector current. Within the resonance chiral theory, and considering the large-Nc expansion, this proces…
Low-Energy Constants from Resonance Chiral Theory
Antonio Pich
I discuss the recent attempts to build an effective chiral Lagrangian incorporating massive resonance states. A useful approximation scheme to organize the resonance Lagrangian is…
Theoretical progress on the V_us determination from tau decays
Elvira Gamiz, Matthias Jamin, Antonio Pich +2
A very precise determination of V_us can be obtained from the semi-inclusive hadronic decay width of the tau lepton into final states with strangeness. The ratio of the Cabibbo-sup…
|V_us| and m_s from hadronic tau decays
Elvira Gamiz, Matthias Jamin, Antonio Pich +2
Recent progress in the determination of |V_us| employing strange hadronic tau-decay data are reported. This includes using the recent OPAL update of the strange spectral function,…
Towards a consistent estimate of the chiral low-energy constants
V. Cirigliano, G. Ecker, M. Eidemuller +3
Guided by the large-Nc limit of QCD, we construct the most general chiral resonance Lagrangian that can generate chiral low-energy constants up to O(p^6). By integrating out the re…
