The inclusive b$\rightarrow$s$\gamma$ decay in the noncommutative standard model

İltan, E.O
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.

The exclusive (B)over-bar ->pi e(+)e(-) and (B)over-bar ->rho e(+)e(-) decays in the two Higgs doublet model with flavor changing neutral currents
Iltan, EO (World Scientific Pub Co Pte Lt, 1999-10-30)
We present the leading logarithmic QCD corrections to the matrix element of the decay b --> de(+)e(-) in the two Higgs doublet model with tree level flavor changing currents (model III). We continue studying the differential branching ratio and the CP-violating asymmetry for the exclusive decays B --> pi e(+)e(-) and B --> pe(+)e(-) and analysing the dependencies of these quantities on the selected model III parameters, xi(U,D), including the leading logarithmic QCD corrections. Further, we present the forw...
The Lorentz and CPT violating effects on the Z -> l(+) l(-) decay
Iltan, EO (Springer Science and Business Media LLC, 2005-03-01)
We study the Lorentz and CPT violating effects on the branching ratio, the CPT violating asymmetry and the ratio of the decay width, including only the Lorentz violating effects, to the one obtained in the standard model, for the flavor dependent part of the lepton flavor conserving Z -> l(+) l(-) (l = e, mu, tau) decay. The inclusion of the Lorentz and CPT violating e. ects in the standard model contribution are too small to be detected, since the corresponding coefficients are highly suppressed at the low...
The form factors existing in the b -> sg* decay and the possible CP violating effects in the noncommutative standard model
Iltan, EO (2002-11-01)
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 fa...
The radiative K* meson decays in QCD
Alıyev, Tahmasıb; Iltan, E (Springer Science and Business Media LLC, 1996-06-01)
The g(K0*K0 gamma) and g(K+*K+gamma) coupling constants and the radiative decay widths are calculated in the context of QCD sum rules. It is found that the discrepancy between the experimental data and theoretical results still exists.
Cagil, A.; Zeyrek, Mehmet Tevfik (Jagiellonian University, 2011-01-01)
In this work, the production processes of heavy neutral scalar and pseudoscalar associated with standard model gauge boson Z(L) at future e(+)e(-) colliders (ILC and CLIC) are examined. The total and differential cross-sections are calculated for the processes in the context of the littlest Higgs model. Dependence of production processes to littlest Higgs model parameters in the range of compatibility with electroweak precision measurements and decays to lepton-flavor violating final states are also analyze...
