We present a complete analysis of the neutral fermion sector of supersymmetric E-6-inspired low-energy models containing an extra SU(2), concentrating on the alternative left-right and inert models. We show that the R-parity conserving scenario always exhibits a large Dirac mass for nu(L) with maximal mixing with an isosinglet neutrino, and that R-parity violating scenarios do not change the picture other than allowing further mixing with another isosinglet. In order to recover standard model phenomenology, additional assumptions in the form of discrete symmetries and/or new interactions are needed. We introduce and investigate the discrete symmetry method and higher-dimensional operators as mechanisms for solving the neutrino mass and mixing problems in these models.

Neutrino masses in effective rank-5 subgroups of E-6. I. Nonsupersymmetric case
Frank, M; Sher, M; Turan, İsmail (American Physical Society (APS), 2005-06-01)
The neutral fermion sectors of E-6-inspired low-energy models, in particular, the alternative left-right and inert models, are considered in detail within the nonsupersymmetric scenario. We show that in their simplest form, these models always predict, for each generation, the lightest neutrino to be a SU(2)(L) singlet, as well as two extra neutrinos with masses of the order of the up-quark mass. In order to recover standard model phenomenology, additional assumptions in the form of discrete symmetries and/...
Double-lepton polarization asymmetries and branching ratio of the B -> gamma l(+)l(-) transition in universal extra dimension
AZİZİ, KAZEM; Pak, N. K.; ŞİRVANLI, BERİN BELMA (2012-02-01)
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 compacti...
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...
Cosmological consequences of Yukawa-unified SUSY with mixed axion/axino cold and warm dark matter
Baer, Howard; Haider, Markus; Kraml, Sabine; Sekmen, Sezen; Summy, Heaya (2009-02-01)
Supersymmetric models with t - b - tau Yukawa unification at M-GUT qualitatively predict a sparticle mass spectrum including first and second generation scalars at the 3-15 TeV scale, third generation scalars at the (few) TeV scale and gluinos in the sub-TeV range. The neutralino relic density in these models typically turns out to lie far above the measured dark matter abundance, prompting the suggestion that instead dark matter is composed of an axion/axino mixture. We explore the axion and thermal and no...
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...
