We predict the branching ratios of the lepton flavor violating Higgs decays H-0 -> e(+/-)mu(+/-), H-0 -> e(+/-)tau(+/-) and H-0 -> mu(+/-)tau(+/-) in the case that the lepton flavor violation is carried by the scalar unparticle mediation. We observe that their branching ratios are strongly sensitive to the unparticle scaling dimension and they can reach the values of the order of 10(-4), for the heavy lepton flavor case and for the small values of the scaling dimension.

LEPTON FLAVOR CONSERVING Z BOSON DECAYS AND SCALAR UNPARTICLE
Iltan, E. O. (World Scientific Pub Co Pte Lt, 2009-02-20)
We predict the contribution of scalar unparticle to the branching ratios of the lepton flavor conserving Z -> l(+)l(-) decays and we study the discrepancy between the experimental and the QED corrected standard model branching ratios. We observe that these decays are sensitive to the unparticle scaling dimension d(u) for its small values, especially for heavy lepton flavor output.
Charged lepton flavor physics and extra dimensions
Iltan, E. I. (World Scientific Pub Co Pte Lt, 2007-06-28)
We estimate the charged lepton electric dipole moments and the branching ratios of radiative lepton flavor violating decays in the framework of the two Higgs doublet model with the inclusion of two extra dimensions. Here, we consider that the new Higgs doublet is accessible to one of the extra dimensions with a Gaussian profile and the fermions are accessible to the other extra dimension with uniform zero-mode profile. We observe that the numerical values of the physical quantities studied enhance with the ...
ANTISYMMETRIC TENSOR UNPARTICLE AND THE RADIATIVE LEPTON FLAVOR VIOLATING DECAYS
Iltan, E. O. (World Scientific Pub Co Pte Lt, 2012-04-20)
We study the contribution of the antisymmetric tensor unparticle mediation to the branching ratios of the radiative lepton flavor violating decays and predict a restriction region for free parameters of the scenario by using experimental upper limits. We observe that the branching ratios of the radiative lepton flavor violating decays are sensitive to the fundamental mass scales of the scenario and to the scale dimension of antisymmetric tensor unparticle. We obtain a more restricted set for the free parame...
The Lorentz and CPT violating effects on H-o -> f(+)f(-) (ZZ, W+W-) decays
Iltan, EO (World Scientific Pub Co Pte Lt, 2004-02-10)
We study the Lorentz and CPT violating effects on the ratio BRLorVio/Br-SM where BRLorVio (BRSM) is the branching ratios coming from the Lorentz violating effects (the SM), for the decays H-0 --> f(+)f(-) (f = quarks and charged leptons) and H-0 --> ZZ(W+W-). We observe that these new effects are too small to be detected, especially for f(+)f(-) output, since the corresponding coefficients are highly suppressed at the low energy scale.
Lepton flavor violating radion decays in the Randall-Sundrum scenario
Iltan, E. O.; Korutlu, B. (IOP Publishing, 2008-06-01)
We predict the branching ratios of the lepton flavor violating radion decays r --> e(+/-)mu(+/-), r --> e(+/-)tau(+/-) and r --> mu(+/-)tau(+/-) in the two Higgs doublet model, in the framework of the Randall-Sundrum scenario. We observe that their branching ratios are at most of the order of 10(-8), for small values of radion mass and they decrease with increasing values of mr. Among these processes, the r --> tau(+/-)mu(+/-) decay would be the most suitable one to measure its branching ratio.
