We predict the branching ratios of the Z -> e(+/-)mu(+/-), Z -> e(+/-)tau(+/-) and Z -> mu(+/-)tau(+/-) decays in the framework of the 2HDM, in the split fermion scenario. We observe that the branching ratios are not sensitive to a single extra dimension; however, this sensitivity is considerably large for two extra dimensions.

Lepton flavor violating Z-boson decays induced by scalar unparticle Iltan, E. O. (Springer Science and Business Media LLC, 2008-07-01) We predict the branching ratios of the lepton-flavor violating Z-boson decays Z -> e(+/-)mu(+/-), Z -> e(+/-)tau(+/-) and Z -> mu +/-tau +/- in the case that the lepton-flavor violation is carried by scalar unparticlemediation. We observe that their BRs are strongly sensitive to the unparticle scaling dimension, and the branching ratios can reach values of the order of 10(-8), for the heavy lepton-flavor case, for small values of the scaling dimension.
Lepton flavor violating Z -> l(1)(+)l(2)(-) decay in the two Higgs doublet model with the inclusion of non-universal extra dimensions Iltan, EO (Springer Science and Business Media LLC, 2005-05-01) We predict the branching ratios of the Z -> e(+/-) mu(+/-), Z -> e(+/-) tau(+/-) and Z -> mu(+/-)tau(+/-) decays in the model III version of the two Higgs doublet model, with the inclusion of one and two spatial non-universal extra dimensions. We observe that the branching ratios are not sensitive to a single extra dimension, however, this sensitivity is considerable for two extra dimensions.
Unparticle physics and lepton flavor violating radion decays in the Randall-Sundrum scenario Iltan, E. O. (Springer Science and Business Media LLC, 2008-07-01) We predict the branching ratios of the lepton flavor violating radion decays r -> e(+/-)mu(+/-), r -> e(+/-)tau(+/-) and r -> mu(+/-)tau(+/-) in the framework of the Randall-Sundrum scenario in which the lepton flavor violation is by scalar unparticle mediation. We observe that their BRs are strongly sensitive to the unparticle scaling dimension and, for small values, the branching ratios can reach values of the order of 10(-8), for the heavy lepton flavor case.
Semileptonic B-s -> D-sJ(2460)l nu decay in QCD Alıyev, Tahmasıb; Özpineci, Altuğ (Springer Science and Business Media LLC, 2007-08-01) Using three point QCD sum rule methods, the form factors relevant to semileptonic B-s -> D-sJ(2460)l nu decay are calculated. The q(2) dependences of these form factors are evaluated and compared with the heavy quark effective theory predictions. The dependence of the asymmetry parameter alpha, characterizing the polarization of the D-sJ meson, on q(2) stop is studied. The branching ratio of this decay is also estimated, and it is shown that it can easily be detected at LHC.
Radiative B-* meson decays in QCD sum rules Alıyev, Tahmasıb; Pak, NK (Springer Science and Business Media LLC, 1997-01-01) The decay constant g(B)* of the B* mesons and the transition amplitudes of the radiative decays B-a* --> B-a gamma are calculated in the frame-work of QCD sum rules. It is shown that the decay rates B* --> B gamma are one order smaller than the corresponding D* meson decays.
