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 dipole moment.

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.
The effects of non-universal extra dimensions on the fermion electric dipole moments in the two Higgs doublet model Iltan, EO (Springer Science and Business Media LLC, 2004-04-01) We study the the effects of non-universal extra dimensions on the electric dipole moments of fermions in the two Higgs doublet model. We observe that the t quark and b quark electric dipole moments are sensitive to the extra dimensions, however, in the case of charged lepton electric dipole moments, this sensitivity is relatively weak.
Electromagnetic Scattering from Obstacles in the Near Field Region of Electrically Large Arrays Cetin, Ramazan; Aydın Çivi, Hatice Özlem; Nepa, Paolo; Manara, Giuliano (2009-09-18) In this paper, an efficient method for the analysis of electromagnetic scattering/radiation from the obstacles nearby electrically large array antennas, with nonuniform excitation, is proposed. The approach is based on the combination of a ray field representation of electrically large arrays and a DFT (Discrete Fourier Transform) based representation of array current distribution. Proposed method is applied to a 2D problem: Radiation of a linear array of 2N+1 infinitely long current elements with tapered c...
Lepton flavor violatingZ→l1+l2−decay in the general two Higgs doublet model Iltan, E. O.; Turan, İsmail (American Physical Society (APS), 2001-11-28) 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.
CP asymmetry in b->sl(+)l(-) decay Alıyev, Tahmasıb; Iltan, E; Pak, NK (1996-07-01) Using the experimental upper bound on the neutron electric dipole moment and the experimental result on the b-->s gamma branching ratio we have calculated the CP asymmetry and Gamma(2HDM)(b-->sl(+)l(-))/Gamma(SM)(b-->sl(+)l(-)). It is shown that in the invariant dilepton mass q(2) region (m(psi)(2),+0.2 GeV2)<q(2)<m(b)(2) the CP asymmetry is maximal and quite detectable.
