Minimal flavour violation waiting for precise measurements of ΔM_s,S_ψphi,A^s_SL, |V_ub|, γ andB⁰_s,d→μ⁺μ⁻

Particle-antiparticle mixing,εK, ΔΓq, ASLq, ACP(Bd→ψKS), ACP(Bs→ψphi) and B→Xs,dγ in the Littlest Higgs model with T-parity

“…In Section 5 we outline our strategy and our goals for the numerical analysis of Section 7. In Section 6 we discuss the benchmark scenarios for the parameters of the LHT model, which we explore in Section 7, where the correlations between various observables can be studied more explicitly than it is possible in the recent model independent analyses in [35,37]- [43]. It is in this section where we address the possible discrepancy between the indirect and direct determinations of the angle β in the UT, its resolution within the LHT model, the enhancements of A CP (B s → ψφ) and A q SL and the size of the corrections to the MFV result for ∆M d /∆M s .…”

“…Equally important, the presence of new mixing angles θ d ij , generally different from θ ij in the CKM matrix, introduces new flavour violating interactions leading to the violation of various relations between K, B d , and B s systems that are characteristic for models with MFV [31,37,47,48]. Precisely the violation of these relations could signal the presence of mirror fermion contributions.…”

“…We will return to investigate this effect numerically in Section 7. Note that it is −ϕ Bs and not +ϕ Bs that enters (3.40) [37].…”

B-Physics at the LHC

“…The rare, hitherto unobserved, decay B 0 s → µ + µ − has a predicted branching ratio of (3.35 ± 0.32)·10 −9 in the SM [7], but this branching ratio is predicted to receive substantial corrections from many of the new particles which might be discovered at the LHC. Indeed, as seen in Figure 2, the branching ratio has discriminating power against a wide area of new physics parameter space.…”

CP violation and limits on New Physics including recent measurements

“…This feature is completely manifest in figure 5(a). In figure 5 we [54] and references therein), which have received significant attention in the literature, may not trivially produce r d /r s = 1. In this sense, within this general framework, NP contributions to the studied mixings should be either small when compared to the SM ones (the repeated successes of the SM strengthen this trend) or significant and involving a richer flavour structure, including new sources of CP violation.…”
