Reanalysis of pion pion phase shifts from K -> pi pi decays
V. Cirigliano, G. Ecker, A. Pich
We re-investigate the impact of isospin violation for extracting the s-wave pion pion scattering phase shift difference delta_0(M_K) - delta_2(M_K) from K -> pi pi decays. Compared…
Electromagnetic effects in Kl3 decays
Vincenzo Cirigliano, Maurizio Giannotti, Helmut Neufeld
We study the radiative corrections to all Kl3 decay modes to leading non-trivial order in the chiral effective field theory, working with a fully inclusive prescription on real pho…
Quantum Resonant Leptogenesis and Minimal Lepton Flavour Violation
Vincenzo Cirigliano, Andrea De Simone, Gino Isidori +2
It has been recently shown that the quantum Boltzmann equations may be relevant for the leptogenesis scenario. In particular, they lead to a time-dependent CP asymmetry which depen…
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…
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…
Grand Unification and the Principle of Minimal Flavor Violation
Benjamin Grinstein, Vincenzo Cirigliano, Gino Isidori +1
Minimal Flavor Violation is an attractive approach to suppress unacceptably large flavor changing neutral currents from beyond the standard model physics at the TeV scale. It can b…
