We study the form factors appearing in the inclusive decay b --> sg*, in the framework of the noncommutative standard model. Here g* denotes the virtual gluon. We get additional structures and the corresponding form factors in the noncommutative geometry. We analyse the dependencies of the form factors to the parameter p Theta k where p (k) are the four momenta of incoming (outgoing) b quark (virtual gluon g*), Theta is a parameter which measures the noncommutativity of the geometry. We see that the form factors are weakly sensitive to this parameter.

The mu -> e gamma and tau ->mu gamma decays with the inclusion of Lorentz and CPT violating effects Iltan, EO (2003-06-01) 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 viol...
The b -> sgg decay in the two and three Higgs doublet models with CP violating effects Goksu, A; Iltan, EO; Solmaz, L (2001-04-20) We study the decay width and CP asymmetry of the inclusive process b --> sgg (g denotes gluon) in the three and two Higgs doublet models with complex Yukawa couplings. We analyze the dependencies of the differential decay width and CP asymmetry to the s-quark energy E-s and CP violating parameter theta. We observe that there exist a considerable enhancement in the decay width and CP asymmetry is at the order of 10(-2). Further, it is possible to predict the sign of C-7(eff) using the CP asymmetry.
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 inclusive b$\rightarrow$s$\gamma$ decay in the noncommutative standard model İltan, E.O (IOP Publishing, 2002-7-29) We study the new structures appearing due to noncommutative effects in the inclusive decay b --> sgamma*, in the standard model. We present the corresponding coefficients which carry the space-space and space-time noncommutativity.
ON GENERALIZED LOCAL SYMMETRIES OF THE SO(2,1) INVARIANT NONLINEAR SIGMA-MODEL BASKAL, S; ERIS, A; SATIR, A (1994-12-19) The symmetries and associated conservation laws of the SO(2,1) invariant non-linear sigma model equations in 1+1 dimensions are investigated. An infinite family of generalized local symmetries is presented and the uniqueness of these solutions is discussed.
