Fe b 20 03 Fourth generation effects in rare B s → l + l − and B s → l + l − γ decays
The contribution of the fourth generation quarks to the rare Bs → l+l− and Bs → l+l−γ decays are studied. Constraints on the extended Cabibbo–Kobayashi–Maskawa matrix elements |VtbV ∗ ts| and |Vt′bV ∗ t′s| are obtained from the existing experimental result for the branching ratio of the B → Xsγ decay. The branching ratios of the above–mentioned decays, as well as the photon spectrum in the Bs →...
متن کاملRare decays B s → l + l − and B → Kl + l − in the topcolor - assisted technicolor model
We examine the rare decays Bs → l+l− and B → Kl+l− in the framework of the topcolor-assisted technicolor (TC2) model. The contributions of the new particles predicted by this model to these rare decay processes are evaluated. We find that the values of their branching ratios are larger than the standard model predictions by one order of magnitude in wide range of the parameter space. The longit...
متن کاملQCD sum rule analysis of the decays B-->Kl+l- and B-->K*l+l-
We use QCD sum rules to calculate the hadronic matrix elements governing the rare decays B → Kl+l− and B → K∗l+l− induced by the flavour changing neutral current b → s transition. We also study relations among semileptonic and rare B → K(∗) decay form factors. The analysis of the invariant mass distribution of the lepton pair in B → K(∗)l+l− and of the angular asymmetry in B → K∗l+l− provides u...
متن کامل6 Probe R - parity Violating Supersymmetry Effects in B → K ( ∗ ) l + l − and B s → l + l − Decays
We study the decays B → K(∗)l+l− and Bs → l+l− (l = e, μ) in the minimal supersymmetric standard model with R-parity violation (RPV). From the recent measurements of their branching ratios, 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 as...
متن کاملB − L Mediated Supersymmetry Breaking
If the superpartners of the standard model fields find out about supersymmetry breaking from the standard gauge interactions, then the superpartner spectrum can be computed in terms of few parameters, and unwanted flavor-changing neutral currents are suppressed. This standard gauge mediated supersymmetry breaking (SGMSB) scenario requires “messenger” superfields charged under the standard gauge...
