Abstract
Recently, the CDF and DØ collaborations have claimed that the CP violating phase in Bs0−B̄s0 mixing is large, which is contrary to the expectations in the Standard Model. Such a large phase suggests New Physics contributions to Bs0−B̄s0 mixing. Motivated by this, we reevaluate the constraints on R-parity violating contributions, including baryon number violating couplings not considered before, to the mixing mass matrix element Ms12 from the recent measurements of Bs0−B̄s0 mixing. We show that present data allow us to put quite strong constraints on both the magnitudes and the weak phases of the R-parity violating parameters. Some of these bounds are better than the exciting ones, and some bounds are obtained for the first time. Near future experiments at the Tevatron, the LHC and B-factories can shrink or reveal the relevant parameter spaces of R-parity violating couplings.

Limits on these products of couplings have been presented in Ref. [ref] for a SUSY mass of $100$ GeV and in [ref] for a mass of $500$ GeV – as explained above, our limits can be confronted to the bounds applying on $∑_iλ'_i13λ'_i31$, etc., in these references.

The similar analysis was performed only from the bound on $ΔM_s$ in Refs. [ref] , in this paper we have used the current bounds not only on $ΔM_s$ but also on $ϕ_s^J/ψϕ$ and $ΔΓ_s$ as given in Eqs. ([ref]-[ref]).

* Almost all bounds on the moduli of $L$ coupling products from current 95% C.L. data of $ΔM_s$, $ϕ_s^J/ψϕ$ and $ΔΓ_s$ are stronger than previous ones in Refs. [ref] , which are obtained only from the 68% C.L. data of $ΔM_s$. $L$ couplings that may contribute to $B_s^0-B̅_s^0$ mixing also affect various decays, relevant $L$ coupling effects in the decays have already been studied in Refs. [ref] , and some moduli of them may have better bounds from the decays.
