Determining chiral couplings at NLO

Ignasi Rosell

We present a general method that allows to estimate the low-energy constants of Chiral Perturbation Theory up to next-to-leading corrections in the 1/N(C) expansion, that is, keepi…

The Standard Model prediction for R_{e/mu}^{(pi,K)}

Vincenzo Cirigliano, Ignasi Rosell

We study the ratios R_{e/mu}^{(P)} = Gamma(P -> e nu [gamma])/Gamma(P -> mu nu [gamma]) (P=pi,K) in Chiral Perturbation Theory to order e^2 p^4. We complement the two-loop effectiv…
