New constraints onR-parity violation fromKandBsystems

Polarizations in decaysBu,d→VVand possible implications forR-parity violating supersymmetry

“…The rich phenomenology implied by RPV couplings in B decays have been extensively discussed in [24,25,26,27,28]. In this paper, we extend these studies to decays B → V V .…”

“…We find that many bounds are stronger than the existing limits [22,24], which may be useful for further studying the RPV SUSY.…”

“…Fortunately, the parameter space is not ruled out yet, the existing upper limit is |λ ′ i23 λ ′ * i22 | < 2.3×10 −3 [22,24]. We note that similar strength of the RPV couplings is also needed in the recent studies to solve the CP problem in B → φK [47] and the η′ puzzle in B → η′K [25].…”

ProbeR-parity violating supersymmetry effects inB→K(*)ℓ+ℓ−

“…The effects of RPV SUSY in B meson decays have been extensively investigated in the literature [21,22]. The decays B → K ( * ) ℓ + ℓ − and B s → ℓ + ℓ − are all induced at the parton level by b → sℓ + ℓ − process, and they involve the same set of the RPV coupling products.…”

“…The individual RPV couplings have been constrained from various low-energy processes [5], and upper limits on some of the product couplings, including their phases, have also been found [6,7,8,9,10,11]. Often one finds that the product coupling is much more constrained than the direct product of the upper bounds of the individual couplings 2 .…”
