Explaining the Bd(s)→K(*)K¯(*) puzzle via a chiral flip in the R -parity violating MSSM with the seesaw mechanism
We study the nonleptonic puzzle of Bd(s)→K(*)K¯(*) decay in the R-parity violating minimal supersymmetric standard model extended with the inverse seesaw mechanism. In this model, the chiral flip of sneutrinos can contribute to the observables LKK¯ and LK*K¯*, that is beneficial for explaining the relevant puzzle. We also find that this unique effect can engage in the Bs−B¯s mixing. We utilize the scenario of complex λ′ couplings to fulfill the recent stringent constraint of Bs−B¯s mixing, and examine other related bounds of B, K-meson decays, lepton decays, neutrino data, Z decays, oblique parameters, CP violations, etc. Besides, inspired by the new measurement of B(B+→K+νν¯) by Belle II, which shows about 2.7σ higher than the Standard Model prediction, we also investigate the New Physics enhancement to this observable.
