Analysis of Bs→φμ+μ- decay within supersymmetry

  • Motivated by the rst measurement on B(Bs→φμ+μ-) by the CDF Collaboration, we study the supersymmetric e ects in semi-leptonic Bs→φμ+μ- decay. In our evaluations, we analyze the dependences of the dimuon invariant mass spectrum and the forward-backward asymmetry on relevant supersymmetric couplings in the MSSM with and without R-parity. The analyses show that the new experimental upper limits of B(Bs→φμ+μ-)from the LHCb Collaboration could further improve the bounds on sneutrino exchange couplings and (δLLu)23 as well as (δLL,RRu)23 mass insertion couplings. In addition, within the allowed ranges of relevant couplings under the constraints from B(Bs→φμ+μ-), B(B→K(*)μ+μ-) and (Bs→φμ+μ-), the dimuon forward-backward asymmetry and the di erential dimuon forward-backward asymmetry of Bs→φμ+μ-are highly sensitive to the squark exchange contribution and the (δLLu)23 mass insertion contribution. The results obtained in this work will be very useful in searching for supersymmetric signals at the LHC.

Analysis of Bs→φμ+μ- decay within supersymmetry

    Corresponding author: WANG Ru-Min,

Abstract: Motivated by the rst measurement on B(Bs→φμ+μ-) by the CDF Collaboration, we study the supersymmetric e ects in semi-leptonic Bs→φμ+μ- decay. In our evaluations, we analyze the dependences of the dimuon invariant mass spectrum and the forward-backward asymmetry on relevant supersymmetric couplings in the MSSM with and without R-parity. The analyses show that the new experimental upper limits of B(Bs→φμ+μ-)from the LHCb Collaboration could further improve the bounds on sneutrino exchange couplings and (δLLu)23 as well as (δLL,RRu)23 mass insertion couplings. In addition, within the allowed ranges of relevant couplings under the constraints from B(Bs→φμ+μ-), B(B→K(*)μ+μ-) and (Bs→φμ+μ-), the dimuon forward-backward asymmetry and the di erential dimuon forward-backward asymmetry of Bs→φμ+μ-are highly sensitive to the squark exchange contribution and the (δLLu)23 mass insertion contribution. The results obtained in this work will be very useful in searching for supersymmetric signals at the LHC.
