We review constraints from quark and lepton flavor violation on extra dimensional models with warped geometry, both in the minimal and the custodial model. For both scenarios, Kaluza-Klein (KK) masses that are large enough to suppress constraints from electroweak precision tests (EWPT) also sufficiently suppress all quark flavor and CP violation, with the exception of CP violation in KK mixing and (to a lesser extend) in DD mixing. In the lepton sector the minimal scenario leads to excessively large contributions to μ → eγ transitions, requiring KK masses of at least 20 TeV or larger.

An exception is the article [19] which emphasises that a precision measurement of ∆Γ d would provide an interesting window to new physics.…”

Motivated by the recent measurement of the dimuon asymmetry by the DØ collaboration, which could be interpreted as an enhanced decay rate difference in the neutral B d -meson system, we investigate the possible size of new-physics contributions to ∆Γ d . In particular, we perform model-independent studies of non-standard effects associated to the dimension-six current-current operators (dp)(p b) with p, p = u, c as well as (db)(τ τ ). In both cases we find that for certain flavour or Lorentz structures of the operators sizeable deviations of ∆Γ d away from the Standard Model expectation cannot be excluded in a model-independent fashion.

CP violation in the Bs0 system

We review experimental and theoretical studies of CP violation in the B 0 s system. Updated predictions for the mixing parameters of the B 0 s mesons expected in the Standard Model (SM) are given, namely the mass difference ∆M SM s = (18.3±2.7) ps −1 , the decay rate difference ∆Γ SM s = (0.085 ± 0.015) ps −1 , and the flavour specific CP asymmetry a s,SM fs = (2.22 ± 0.27) × 10 −5 and the equivalent quantities in the B 0 -sector. Current experimental values of ∆Ms and ∆Γs agree with remarkable precision with theoretical expectations. This agreement supports the applicability of theoretical tools such as the Heavy Quark Expansion (HQE) to these decays. CP violating studies in the B 0 s system provide essential information to test the SM expectations, and to unveil possible contribution of the new physics (NP). NP effects on ∆Ms of the order of 15% are still possible. The CP phase φs due to CP violation in interference of decays and mixing can accommodate effects of the order of O(100%). The semileptonic CP asymmetry a s sl due to CP violation in mixing could still be a factor of 130 larger than its robust SM expectation and thus provides a very clean observable for NP searches. Theoretical improvements that are necessary to make full use of the experimental precision are discussed.
