Resonance saturation at next-to-leading order
Ignasi Rosell
A proper estimation of the chiral low-energy constants of Chiral Perturbation Theory is a very important task. To this end resonance chiral Lagrangians have been used fruitfully. W…
Resonance saturation of the chiral couplings at NLO in 1/Nc
Ignasi Rosell, Pedro Ruiz-Femenia, Juan Jose Sanz-Cillero
The precision obtainable in phenomenological applications of Chiral Perturbation Theory is currently limited by our lack of knowledge on the low-energy constants (LECs). The assump…
pi/K -> e nu branching ratios to O(e^2 p^4) in Chiral Perturbation Theory
Vincenzo Cirigliano, Ignasi Rosell
We calculate the ratios R_{e/mu}^{(P)} = Gamma(P -> e nu)/Gamma (P -> mu nu) (P=pi,K) in Chiral Perturbation Theory to order e^2 p^4. We complement the one- and two-loop effective…
Vanishing chiral couplings in the large-N_C resonance theory
Jorge Portoles, Ignasi Rosell, Pedro Ruiz-Femenia
The construction of a resonance theory involving hadrons requires implementing the information from higher scales into the couplings of the effective Lagrangian. We consider the la…
