Abstract

We examine the possible resolution of the recently observed polarization anomaly in B0(B̄0)→ K*0(K̄*0)-decay within R-parity violating (Rp) SUSY. We show that a combination of the superpotential trilinear Rp-interactions, with the couplings λ′, and the soft SUSY breaking bilinear Rp sneutrino-Higgs mixing, proportional to μ∼2, can potentially generate the effective operators with the chirality structure necessary to account for this anomaly. However, we demonstrate that the existing experimental data on Bs→μ+μ - decay lead to stringent upper limits on the Wilson coefficients of these operators, which are about 2 orders of magnitude below the values required for the resolution of the B-decay polarization anomaly, and, therefore, it can hardly be explained within the Rp SUSY framework. As a byproduct result of our analysis we derive new limits on the products of the soft bilinear and the superpotential trilinear Rp-parameters of the form μ∼2λ′. © 2007 The American Physical Society.
