Abstract

We calculate contributions to B{sub s}-B{sub s} mixing through tree-level sneutrino exchange in the framework of the minimal supersymmetric standard model with R-parity violation, including the next-to-leading-order QCD corrections. We compare our results with the updated bounds on the B{sub s}-B{sub s} mass difference reported by CDF collaborations and present new constraints on the relevant combinations of parameters of the minimal supersymmetric standard model with R-parity violation. Our results show that upper bound on the relevant combination of couplings of B{sub s}-B{sub s} mixing is of the order 10{sup -9}. We also calculate the B{sub d}{sup 0}-B{sub d}{sup 0} and K{sup 0}-K{sup 0} mass differences and show that the upper bounds on the relevant combinations of couplings are 2 and 4 orders of magnitude stronger than ones reported in the literatures, respectively. We also discuss the case of complex couplings and show that how the relevant combinations of couplings are constrained by the updated experiment data of B{sub s}-B{sub s}, B{sub d}-B{sub d} mixing and time-dependent CP asymmetry S{sub J/{psi}}{sub K{sub s}}, and future possible observations of S{sub J/{psi}}{sub {phi}} at the Large Hadron Collider beauty experiment (LHCb), respectively.

Study of the semileptonic decay D{sub s}{sup +}{yields}f{sub 0}(980)e{sup +}{nu} and implications for B{sub s}{sup 0}{yields}J/{psi}f{sub 0}

Journal Article Ecklund, K M ; He, Q ; Insler, J ; ... - Physical Review. D, Particles Fields

Using e{sup +}e{sup -}{yields}D{sub s}{sup -}D{sub s}*{sup +} and D{sub s}*{sup -}D{sub s}{sup +} interactions at 4170 MeV collected with the CLEO-c detector, we investigate the semileptonic decays D{sub s}{sup +}{yields}f{sub 0}(980)e{sup +}{nu} and D{sub s}{sup +}{yields}{phi}e{sup +}{nu}. By examining the decay rates as functions of the four-momentum transfer squared q{sup 2}, we measure the ratio [(dB/dq{sup 2})(D{sub s}{sup +}{yields}f{sub 0}(980)e{sup +}{nu})B(f{sub 0}{yields}{pi}{sup +}{pi}{sup -})]/[(dB/dq{sup 2})(D{sub s}{sup +}{yields}{phi}e{sup +}{nu})B({phi}{yields}K{sup +}K{sup -})] at q{sup 2} of zero to be (42{+-}11)%. This ratio has been predicted to equal the rate ratio [B(B{sub s}{yields}J/{psi}f{sub 0})B(f{sub 0}{yields}{pi}{sup +}{pi}{sup -})]/[B(B{sub s}{yields}J/{psi}{phi})B({phi}{yields}K{sup +}K{sup -})], thus indicatingmore »« less

Rare decays B{sub u}{sup +}{yields}{pi}{sup +}l{sup +}l{sup -}, {rho}{sup +}l{sup +}l{sup -} and B{sub d}{sup 0}{yields}l{sup +}l{sup -} in the R-parity violating supersymmetry

Journal Article Jianjun, Wang ; Department of Physics, Henan Normal University, XinXiang, Henan 453007 ; Rumin, Wang ; ... - Physical Review. D, Particles Fields

We study the rare decays B{sub u}{sup +}{yields}{pi}{sup +}l{sup +}l{sup -}, {rho}{sup +}l{sup +}l{sup -} and B{sub d}{sup 0}{yields}l{sup +}l{sup -} (l=e, {mu}) in the R-parity violating supersymmetric standard model. From the latest upper limits of B(B{sub u}{sup +}{yields}{pi}{sup +}l{sup +}l{sup -}) and B(B{sub d}{sup 0}{yields}l{sup +}l{sup -}), we have derived new upper bounds on the relevant R-parity violating couplings products, which are stronger than the existing ones. Using the constrained parameter space, we present the R-parity violating effects on the branching ratios and the forward-backward asymmetries of these decays.

Studying double charm decays of B{sub u,d} and B{sub s} mesons in the MSSM with R-parity violation

Journal Article Kim, C S ; Rumin, Wang ; Yadong, Yang - Physical Review. D, Particles Fields

Motivated by the possible large direct CP asymmetry of B{sub d}{sup 0}{yields}D{sup +}D{sup -} decays measured by the Belle Collaboration, we investigate double charm B{sub u,d} and B{sub s} decays in the minimal supersymmetric standard model with R-parity violation. We derive the bounds on relevant R-parity violating couplings from the current experimental data, which show quite consistent measurements among relative collaborations. Using the constrained parameter spaces, we explore R-parity violating effects on other observables in these decays, which have not been measured or have not been well measured yet. We find that the R-parity violating effects on the mixing-induced CPmore »« less

Probing new physics in B{yields}f{sub 0}(980)K decays

Journal Article Giri, A K ; Mawlong, B ; Mohanta, R - Physical Review. D, Particles Fields

We study the hadronic decay modes B{sup {+-}}{sup (0)}{yields}f{sub 0}(980)K{sup {+-}}{sup (0)}, involving a scalar and a pseudoscalar meson in the final state. These decay modes are dominated by the loop induced b{yields}sqq(q=s,u,d) penguins along with a small b{yields}u tree level transition (for B{sup +}{yields}f{sub 0}K{sup +}) and annihilation diagrams. Therefore, the standard model expectation of direct CP violation is negligibly small and the mixing-induced CP violation parameter in the mode B{sup 0}{yields}f{sub 0}K{sub S} is expected to give the same value of sin(2{beta}), as extracted from B{sup 0}{yields}J/{psi}K{sub S} but with opposite sign.

Probe R-parity violating supersymmetry effects in B{yields}K{sup (*)}l{sup +}l{sup -} and B{sub s}{yields}l{sup +}l{sup -} decays

Journal Article Yuanguo, Xu ; Yadong, Yang ; Rumin, Wang ; ... - Physical Review. D, Particles Fields

We study the decays B{yields}K{sup (*)}l{sup +}l{sup -} and B{sub s}{yields}l{sup +}l{sup -}(l=e,{mu}) in the minimal supersymmetric standard model with R-parity violation (RPV). From the recent measurements of B(B{yields}K{sup (*)}l{sup +}l{sup -}) and the upper limits of B(B{sub s}{yields}l{sup +}l{sup -}), we have derived new upper bounds on the relevant RPV coupling products, which are stronger than the existing ones. Using the constrained parameter space, we predict the RPV effects on the forward-backward asymmetries A{sub FB}(B{yields}K{sup (*)}l{sup +}l{sup -}) and the branching ratios B(B{sub s}{yields}l{sup +}l{sup -}). Our results of the forward-backward asymmetries agree with the recent experiment data. Itmore »« less
