We study the radiative decay phi --> pi (0)pi (0)gamma within the framework, of a phenomenological approach in which the contributions of sigma mesons, rho mesons, and f(0) mesons are considered. We analyze the interference effects between different contributions and, utilizing the experimental branching ratio for this decay, we estimate the coupling constant g(phi sigma gamma).

Decay rho(0)->pi(+)+pi(-)+gamma and the coupling constant g(rho sigma gamma) Gokalp, A; Yılmaz, Osman (2000-11-01) The experimental branching ratio for the radiative decay rho (0)-pi (+) + pi (-) + gamma is used to estimate the coupling constant g(rho sigma gamma) for a set of values of sigma -meson parameters M-sigma and Gamma (sigma). Our results are quite different than the values of this constant used in the literature.
Tensor form factors of B -> K-1 transition from QCD light cone sum rules Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-05-30) The tensor form factors of B into p-wave axial vector meson transition are calculated within light cone QCD sum rules method. The parametrizations of the tensor form factors based on the series expansion are presented.
Scalar f(0) and a(0) mesons in radiative phi -> K+K-gamma decay Gokalp, A.; Ozturk, F.; Yılmaz, Osman (Elsevier BV, 2009-01-26) We study the radiative phi -> K+K-gamma decay within a phenomenological framework by considering the contributions of the f(0)(980) and a(0)(980) scalar resonances. We consider the kaon-loop model and the no-structure model to evaluate these contributions and compare the results obtained in two models.
Strong Coupling Constants of Negative Parity Heavy Baryons with pi and K Mesons Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2017-01-01) The strong coupling constants of negative parity heavy baryons belonging to sextet and antitriplet representations of SUf(3) with light pi and K mesons are estimated within the light cone QCD sum rules. It is observed that each class of the sextet-sextet, sextet-antitriplet, and antitriplet-antitriplet transitions can be described by only one corresponding function. The pollution arising from the positive to positive, positive to negative, and negative to positive parity baryons transitions is eliminated by...
Rare B -> l(+)l(-)gamma decay and new physics effects Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2001-11-08) Using the most general, model independent form of the effective Hamiltonian rare decays B --> l(+)l(-)gamma (l = mu, tau) are studied. The sensitivity of the photon energy distribution and branching ratio to the new Wilson coefficients is investigated.
