We calculate lepton flavor violating Z-->l(1)(+)l(2)(-) decay in the framework of the general two Higgs doublet model. In our calculations we use the constraints for the Yukawa couplings (xi) over bar (D)(N,taue) and (xi) over bar (D)(N,taumu) coming from the experimental result of the muon electric dipole moment and upper limit of BR(mu-->egamma). We observe that it is possible to reach the present experimental upper limits for the branching ratios of such Z decays in model III.

Lepton flavor conserving Z -> l(+)l(-) decays in the general two Higgs doublet model Iltan, EO (2002-02-01) We calculate the new physics effects to the branching ratios of the lepton flavor conserving decays Z - l(+)l(-) in the framework of the general two Higgs doublet model. We predict the upper limits for the couplings \(xi) over bar (D)(N,mutau)\ and \(xi) over bar (D)(N,tautau)\ as 3 x 10(2) GeV and 1 x 10(2) GeV, respectively.
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.
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.
LEPTON FLAVOR VIOLATING HIGGS DECAYS AND UNPARTICLE PHYSICS Iltan, E. O. (World Scientific Pub Co Pte Lt, 2009-06-07) 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.
Anomalous magnetic moment of the muon in the two Higgs doublet model Iltan, EO; Sundu, H (2003-02-01) We calculate the new physics effects on the anomalous magnetic moment of the muon in the framework of the two Higgs doublet model. We predict an upper bound for the lepton flavor violating coupling, which is responsible for the point like interaction between muon and tau, by using the uncertainty in the experimental result of the muon anomalous magnetic moment. We show that the upper bound predicted is more stringent compared to the one which is obtained by using the experimental result of the muon electric...
