We study the radiative decays omega --> etapi(o)gamma and rho(o) --> etapi(o)gamma within the framework of a phenomenological approach in which the contributions of the intermediate a(o)-meson and intermediate vector meson states are considered. We conclude that although the ao-meson intermediate state amplitude makes a small contribution to omega --> etapi(o)gamma decay, it makes a substantial contribution to rho(o) --> etapi(o)gamma decay.

Radiative lepton flavor violating decays in the Randall-Sundrum background with localized leptons Iltan, E. O. (World Scientific Pub Co Pte Lt, 2008-03-20) We study the radiative lepton. avor violating l(i)-> l(j) gamma decays in the two- Higgs doublet model, respecting the Randall-Sundrum scenario and estimate the contributions of the KK modes of left- ( right-) handed charged lepton doublets ( singlets) on the branching ratios. We observe that the branching ratios are sensitive to the contributions of the charged lepton KK modes.
Bq→l+l−γdecays in light cone QCD Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (American Physical Society (APS), 1997-6-1) The radiative dileptonic decays B-s(B-d)-->l(+)l(-)gamma (l=e,mu) are investigated within the standard model. The transition form factors are calculated in the framework of the light cone QCD sum rule method and it is found that the branching ratios are B(B-s-->e(+)e(-)gamma) = 2.35 x 10(-9), B(B-s-->mu(+)mu(-)gamma) = 1.9 x 10(-9) B(B-d-->e(+)e(-)gamma) = 1.5 x 10(-10), and B(B-d-->mu(+)mu(-)gamma) = 1.2 x 10(-10). A comparison of our results with the constituent quark model predictions on the branching ra...
Fourth generation effects in rare exclusive B -> K*l(+)l(-) decay Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2000-10-02) Influence of the fourth generation, if ever exists, on the experimentally measurable quantities such as invariant dilepton mass distribution, lepton forward-backward asymmetry, and the ratio Gamma(L)/Gamma(T) of the decay widths when K* meson is longitudinally and transversally polarized, is studied. Using the experimental results on the branching ratios for the B --> X(s)gamma and semileptonic B --> X(c)l (v) over bar decays, the two possible solutions of the 4 x 4 Cabibbo-Kobayashi-Maskawa factor Vt'sVt'b...
Light cone QCD sum rule analysis of B->Kl(+)l(-) decay Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (1997-05-08) We calculate the transition formfactors for the B --> Kl(+)l(-) decay in the framework of the light cone QCD sum rules. The invariant dilepton mass distribution and the final lepton longitudinal polarization asymmetry are investigated. The comparison analysis of our results with traditional sum rules method predictions on the formfactors is performed. (C) 1997 Elsevier Science B.V.
Exclusive radiative weak decays of B-c meson in light cone QCD Alıyev, Tahmasıb; Savcı, Mustafa (1998-12-01) We investigate the radiative B-c --> p(+)gamma and B-c --> K*(+gamma) decays in the standard model. The transition form factors are calculated in the framework of the light cone QCD sum rules method. We estimate the branching ratios of the B-c --> p(+)gamma and B-c --> K*(+)gamma decays.
