On-shell renormalization of neutralino and chargino mass matrices in R-parity violating models - Correlation between LSP decays and neutrino mixing angles revisited

摘要

We present an on-shell renormalization scheme for the neutralino and charginomass matrices for two R-parity violating models, namely bilinear R-parityviolation and the munuSSM with one right-handed neutrino superfield. We discussin both models how to obtain neutrino masses and mixing angles correctly aswell as differences to the existing DRbar calculations. Both models predictcorrelations between neutrino mixing angles and ratios of R-parity violatingdecays such as neutralino_1 -> l W which can be tested for example at the LHC.We point out that there are cases where one has to include the complete NLOcorrections for the decays neutralino_1 -> l W to predict reliably thecorrelations between neutrino- and collider-physics. Moreover, we discussbriefly the implementation of these decays in the public program CNNDecays.
