B to strange tensor meson transition in a model with one universal extra dimension

Abstract

We analyze the semileptonic B → K * 2 (1430)l + l − transition in universal extra dimension model. In particular, we present the sensitivity of related observables such as branching ratio, polarization distribution and forward-backward asymmetry to the compactification factor (1/R) of extra dimension. The obtained results from extra dimension model show overall a considerable deviation from the standard model predictions for small values of the compactification factor. This can be considered as an indication for existence of extra dimensions.

Double-lepton polarization asymmetries and branching ratio of the B → γl + l − transition in universal extradimension

“…is suppressed (for details see [17]), the branching ratio is suppressed at small values of 1/R. This is against the effect of the UED in some semileptonic decay channels considered for instance in [12,17].…”

“…Under above discussion on the compactification factor, we will take the 1/ > 500 in this paper. The effective Hamiltonian of several FCNC processes [23,24], semileptonic and radiative decays of B mesons [25][26][27][28][29][30][31][32][33], and FCNC baryonic decays [34][35][36] have been investigated in the ACD model. Polarization properties of final state particles in semileptonic decays, which is an powerful tool in searching new physics beyond the SM, have also been studied widely besides the other observables in these works, e.g., [17,25,29,33].…”

Analysis of the radiativeΛb→Λγtransition in the standard model and scenarios with one or two universal extra dimensions

“…There are many works dedicated to the analysis of different decay channels in the UED5 in the literature (for some of them, see Refs. [3,[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]). However, the number of works devoted to the applications of the UED6 is relatively few.…”
