Majorana neutrinos with effective interactions in B decays

Abstract: We investigate the possible contribution of intermediate Majorana neutrinos to B meson decays in an interaction formalism with dim 6 effective operators. We exploit the existing bounds on the lepton number violating B^- -> mu^-mu^- pi^+ and in the radiative B^- -> mu^- nu gamma decays to constrain the new physics contributions, characterized by their Dirac-Lorentz structure. We propose studying tau lepton polarization and lepton-photon angular asymmetries in tauonic and radiative B decays at B factories as a means to evaluate and disentangle the trails of the distinct effective operators

Latin American Webinars on Physics (LAWPhysics)

Series comments: The lawphysics is a webinar cycle created to connect physicists working on astroparticles, high energy physics, and astrophysics. Every webinar is broadcasted in youtube where they are always available for consulting and watching. The webinars take place every two or three weeks, on Wednesday at 15:00 GMT. The whole transmission lasts 60 minutes including questions and debates from the participants.
