We study the Lorentz and CPT violating effects on the branching ratio and the CP violating asymmetry of the lepton flavor violating interactions mu --> egamma and tau --> mugamma, in the model III version of the two Higgs doublet model. Here we consider that the Lorentz and CPT violating effects exist in the QED part of the interactions and enter into expressions in the lepton propagators and in the lepton-photon vertex. We observe that there exists a non-zero CP asymmetry. However, the Lorentz and CPT violating effects on the braching ratio and the CP asymmetry are negligibly small.

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.
The Lorentz and CPT violating effects on the Z -> l(+) l(-) decay Iltan, EO (Springer Science and Business Media LLC, 2005-03-01) We study the Lorentz and CPT violating effects on the branching ratio, the CPT violating asymmetry and the ratio of the decay width, including only the Lorentz violating effects, to the one obtained in the standard model, for the flavor dependent part of the lepton flavor conserving Z -> l(+) l(-) (l = e, mu, tau) decay. The inclusion of the Lorentz and CPT violating e. ects in the standard model contribution are too small to be detected, since the corresponding coefficients are highly suppressed at the low...
The effect of the location of the new Higgs doublet on the radiative lepton flavor violating decays in the split fermion scenario Iltan, E. O. (Springer Science and Business Media LLC, 2006-05-01) We study the branching ratios of the lepton flavor violating processes mu -> e gamma, tau -> e gamma and tau -> mu gamma in the split fermion scenario, with the assumption that the new Higgs doublet is restricted to the 4D brane (thin bulk) in one and two extra dimensions, in the framework of the two Higgs doublet model. We observe that the branching ratios are sensitive to the location of the 4D brane and, in the second case, the width of the thin bulk, especially for the mu -> e gamma decay.
The decay tau ->mu(nu)over-bar(i)nu(i) in the Randall-Sundrum background with localized U(1)(Y) gauge boson Iltan, E. O.; SUNDU PAMUK, HAYRİYE (Springer Science and Business Media LLC, 2008-02-01) We study the effects of localization of the U(1)(Y) gauge boson around the visible brane and the contributions of the Kaluza-Klein modes of Z bosons on the branching ratio of the lepton flavor violating tau ->mu(nu) over bar (i)nu(i) decay. We observe that the branching ratio is sensitive to the amount of localization of the Z boson in the bulk of the Randall - Sundrum background.
