Double-Lepton Polarization Asymmetries and Polarized Forward Backward Asymmetries in The Rare b → sl+l− Decays in a Single Universal Extra Dimension Scenario
We study the double-lepton polarization asymmetries and single and double-lepton polarization forward backward asymmetries of the rare b → sl+l− mode within the Standard Model and in the Appelquist-Cheng-Dobrescu model, which is a new physics scenario with a single universal extra dimension. In particular, we examine the sensitivity of the observables to the radius R of the compactified extra-d...
متن کاملThe Impact of Universal Extra Dimensions on the Unitarity Triangle and Rare K and B Decays
We calculate the contributions of the Kaluza-Klein (KK) modes to the KL − KS mass difference ∆MK , the parameter εK , the B 0 d,s − B̄0 d,s mixing mass differences ∆Md,s and rare decays K+ → π+νν̄, KL → π0νν̄, KL → μ+μ−, B → Xs,dνν̄ and Bs,d → μμ̄ in the Appelquist, Cheng and Dobrescu (ACD) model with one universal extra dimension. For the compactification scale 1/R = 200 GeV the KK effects in these...
متن کاملExclusive B → K 1 l + l − decay in model with single universal extra dimension
Decay rate and forward-backward asymmetries in B → K1ll , K1 is the axial vector meson, are calculated in the universal extra dimension (UED) model. The dependence of these physical quantities on the compactification radius R, the only unknown paramter in UED model, is studied and it is shown that zero of forward-backward asymmetry is sensitive to the UED model, therefore they can be very usefu...

Exclusive rare B → Kll, B → Kνν̄ and B → K∗γ decays are studied within the Applequist-ChengDobrescu model, an extension of the Standard Model in presence of universal extra dimensions. In the case of a single universal extra dimension compactified on a circle of radius R, we study the dependence of several observables on 1/R, and discuss whether the hadronic uncertainty due to the form factors o...

We study the rare semileptonic and radiative leptonic B s decays in the universal extra dimension model. In this scenario, with a single extra dimension, there exists only one new parameter beyond those of the standard model, which is the inverse of the compactification radius R. We find that with the additional contributions due to the KK modes the branching ratios of the rare B s decays are e...
