August 2000 b → s l + l − decays in and beyond the Standard Model 1

چکیده
We briefly review the status of rare radiative and semileptonic b → s(γ, ll), (l = e, μ) decays. We discuss possible signatures of new physics in these modes and emphazise the role of the exclusive channels. In particular, measurements of the Forward-Backward asymmetry in B → Kll decays and its zero provide a clean test of the Standard Model, complementary to studies in b → sγ decays. Further, the Forward-Backward CP asymmetry in B → Kll decays is sensitive to possible non-standard sources of CP violation mediated by flavor changing neutral current Z-penguins.

The possibility to test the unitarity triangle of CKM matrix is examined by using the semileptonic rare B decays, B → Xq l l− with q = d, s and l’s are leptons. The discussion is emphasized on the CP asymmetry in the framework of standard and beyond the standard models. For the beyond standard model, a minimal extension of the standard model containing an additional isosinglet charge (-1/3) cha...

The flavor changing transitions in the c → uγ, c → uγγ and c → ul + l − offer the possibility to search for new physics in the charm sector. We investigate dominant decay mechanisms in the radiative decays D → V γ, D → P (V)l + l − , D → γγ and we discuss chances to see physics beyond the standard model in these decays. In addition, we analyze Cabibbo allowed D → Kπγ decays with nonresonant Kπ,...
متن کاملThe Effects of Non - Local Operators in Rare B Decays , B → X s l + l −
The effects of non-local operators in rare B decays, B → X s l + l − , are investigated through the model independent analysis. It deals with complete twelve four-Fermi interactions, including two non-local ones which are constrained by the experimental result of the B → X s γ decay. The branching ratio and the forward-backward asymmetry are studied as functions of the twelve Wilson coefficient...

I review the phenomenology of new physics in low energy processes using the notion of minimal flavor violation (vs. non-minimal flavor violation). I compare the predictions of beyond-the-standard models and show that among certain observables in rare b-decays pattern arise, which allow to distinguish between extensions of the Standard Model. I discuss the status and future of the model independ...
