Scalar mesons in radiative ϕ\to K^0\bar{K}^0γdecay

A. Gokalp, C. S. Korkmaz, O. Yilmaz

We study the radiative $ϕ \to K^{0} K ˉ^{0} γ$ decay within a phenomenological framework by considering the contributions of the $f_{0} (980)$ and $a_{0} (980)$ scalar resonances. We ca…

VMD, chiral loops, sigma-meson, and omega-rho mixing in omega-->pi^0 pi^0 gamma decay

A. Gokalp, A. Kucukarslan, O. Yilmaz

In an attempt to explain the latest experimental result about the branching ratio of $ω \to π^{0} π^{0} γ$ decay we reexamine the decay mechanism of this decay in a phenomenological frame…

Scalar $a_{0} (980)$ meson in $ϕ \to π^{0} η γ$ decay

A. Gokalp, A. Kucukarslan, S. Solmaz +1

We study the radiative decay $ϕ \to π^{0} η γ$ within the framework of a phenomenological approach in which the contributions of $ρ$ -meson, chiral loop and $a_{0}$ -meson are considered.…

The $ω σ γ$ -vertex in light cone QCD sum rules

A. Gokalp, O. Yilmaz

We investigate the $ω σ γ$ -vertex and estimate the coupling constant g $_{ω σ γ}$ in the framework of the light cone QCD sum rules. We compare our result with the values of this couplin…

Coupling constants g $_{a_{0} ω γ}$ and g $_{a_{0} ρ γ}$ as derived from QCD sum rules

A. Gokalp, O. Yilmaz

We consider the two point correlation function of scalar current in QCD sum rules approach to estimate the overlap amplitude of $a_{0}$ meson. We then employ QCD sum rules to calcula…

The coupling constant g $_{ρ σ γ}$ as derived from QCD sum rules

A. Gokalp, O. Yilmaz

We employ QCD sum rules to calculate the coupling constant g $_{ρ σ γ}$ by studying the three point $ρ σ γ$ -correlation function. Our results is consistent with the value of this coup…
