We study the radiative dileptonic B ->gamma l(+)l(-) transition in the presence of a universal extra dimension in the Applequist-Cheng-Dobrescu model. In particular, using the corresponding form factors calculated via light cone QCD sum rules, we analyze the branching ratio and double lepton polarization asymmetries related to this channel and compare the results with the predictions of the standard model. We show how the results deviate from predictions of the standard model at lower values of the compactification factor (1/R) of extra dimension.

The mu -> e gamma and tau ->mu gamma decays in the general two Higgs doublet model with the inclusion of one universal extra dimension
Iltan, EO (2004-02-01)
We study the effect of one universal extra dimension on the branching ratios of the lepton flavor violating processes mu --> egamma and tau --> mugamma in the general two Higgs doublet model. We observe that these new effects are tiny for the small values of the compactification radius R. Furthermore, we see that these effects are comparable with the branching ratio obtained without including extra dimension, if the neutral Higgs bosons are nearly degenerate and the complexity of the Yukawa coupling, induci...
The effects of non-universal extra dimensions on the radiative lepton flavor decays mu -> e gamma and tau ->mu gamma in the two Higgs doublet model
Iltan, EO (2004-08-01)
We study the effect of non-universal extra dimensions on the branching ratios of the lepton flavor violating processes mu --> egamma and tau --> mugamma in the general two Higgs doublet model. We observe that these effects are small for a single extra dimension, however, in the case of two extra dimensions there is a considerable enhancement in the additional contributions.
Double-lepton polarization asymmetries and branching ratio in B -> K-0(*)(1430)l(+)l(-) transition from universal extra dimension model
ŞİRVANLI, BERİN BELMA; AZİZİ, KAZEM; İpekoğlu, Yusuf (Springer Science and Business Media LLC, 2011-01-01)
We investigate the B -> K-0(*)(1430)l(+)l(-) transition in the Applequist-Cheng-Dobrescu model in the presence of a universal extra dimension. In particular, we calculate double lepton polarization asymmetries and branching ratio related to this channel and compare the obtained results with the predictions of the standard model. Our analysis of the considered observables in terms of radius R of the compactified extra-dimension as the new parameter of the model show a considerable discrepancy between the pre...
Double-lepton polarization asymmetries and polarized forward backward asymmetries in the rare b -> sl(+)l(-) decays in a single universal extra dimension scenario
BASHIRY, VALİ; Bayar, M.; Azizi, K. (American Physical Society (APS), 2008-08-01)
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 dimension, which is the new parameter in this new physics model.
Exploring extra dimensions through rare processes
Şimşek, Kağan; Turan, İsmail; Department of Physics (2019)
We study the single top quark production and decay mechanisms at one-loop level occurring via flavor-changing neutral currents in the Minimal Universal Extra Dimensions (MUED) model. We make a complete study of the model in the Feynman gauge. Especially, we focus on extracting the complete list of 3- and 4-point interactions and determining the mixings among the gauge eigenstates to form the so-called mass eigenstates. Once we have the complete model analyzed, it is implemented via the LanHEP package and tr...
