Sigma-meson and omega-rho mixing effects in omega --> pi^+ pi^- gamma decay
A. Gokalp, A. Kucukarslan, S. Solmaz +1
We calculate the branching ratio of omega --> pi^+ pi^- gamma decay in a phenomenological framework in which the contributions of VMD, chiral loops, sigma-meson intermediate state…
Collisional Effects in Isovector Response Function of Nuclear Matter at Finite Temperature
S. Ayik, A. Gokalp, O. Yilmaz +1
The dipole response function of nuclear matter at zero and finite temperatures is investigated by employing the linearized version of the extended TDHF theory with a non-Markovian…
-Meson Photoproduction on Nucleons In the Near Threshold Region
H. Babacan, T. Babacan, A. Gokalp +1
The -meson photoproduction, , is studied in the framework of a model, containing -meson exchange in t-channel and nucleon-exchange in s- and u-channels. Consideri…
A Theoretical Study of -Photoproduction on Nucleons near Threshold
H. Babacan, T. Babacan, A. Gokalp +1
We investigate the possibility that the process of -meson photoproduction on proton, , in the near threshold region GeV, can be considered in the fr…
Optimization of finite-range effective interaction for in-medium cross sections
Denis Lacroix, Sakir Ayik, Osman Yilmaz +1
In order to incorporate the finite range effect into effective interactions, a modification of the Skyrme force by introducing a cut-off factor for high momentum transfers is propo…
