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…
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…
One-loop Renormalization of Resonance Chiral Theory: Scalar and Pseudoscalar Resonances
I. Rosell, P. Ruiz-Femenia, J. Portoles
We consider the Resonance Chiral Theory with one multiplet of scalar and pseudoscalar resonances, up to bilinear couplings in the resonance fields, and evaluate its beta-function a…
<VAP> Green Function in the Resonance Region
V. Cirigliano, G. Ecker, M. Eidemuller +2
We analyse the <VAP> three-point function of vector, axial-vector and pseudoscalar currents. In the spirit of large N_C, a resonance dominated Green function is confronted with the…
