Rare and CP-violatingKandBdecays in the Littlest Higgs model with T-parity

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 7 we will see that in the most interesting scenarios the structure of V Hd is very different from the CKM one implying significantly different mirror unitarity triangles than the one following from (2.19). This issue is also discussed in [36], where our analysis is generalized to rare K and B decays.…”

“…These are in particular the mixing induced CP asymmetries S ψK S and S ψφ but also ∆M d /∆M s , A q SL and ∆Γ q . This also applies to Br(B → X s,d γ), the related CP asymmetries and a number of rare decay branching ratios with the latter considered in a separate paper [36].…”

“…• We introduce the concept of the "mirror unitarity triangle" which is also useful when the analysis is generalized to include rare K and B decays [36].…”

“…Generalizations to include rare K and B decays in this determination have been very recently presented in [36].…”

“…Finally, at the beginning of the next decade the very clean decays K + → π + νν and K L → π 0 νν and useful decays K L → π 0 + − could provide decisive tests of the LHT model. A detailed analysis of all these processes in the LHT model has been presented very recently in [36]. The analytic expressions for the short distance functions X, Y and Z given there should allow to perform this program once the data on several FCNC processes listed above will be available.…”
