Explaining the puzzle via chiral-flip in -parity violating MSSM with seesaw mechanism
arXiv:2410.04348 · doi:10.1103/PhysRevD.111.095032
Abstract
We study the non-leptonic puzzle of decay in the -parity violating minimal supersymmetric standard model (RPV-MSSM) extended with the inverse seesaw mechanism. In this model, the chiral flip of sneutrinos can contribute to the observables and , that is benefit for explaining the relevant puzzle. We also find that this unique effect can engage in the - mixing. We utilize the scenario of complex couplings to fulfill the recent stringent constraint of - mixing, and examine other related bounds of -meson decays, lepton decays, neutrino data, decays, oblique parameters, CP violations (CPV), etc. Besides, inspired by the new measurement of by Belle II, which shows about higher than the Standard Model (SM) prediction, we also investigate the New Physics (NP) enhancement to this observable.
