We study the omega --> pi pi gamma decays by adding to the amplitude calculated within the framework of chiral perturbation theory and vector meson dominance the amplitude of sigma -meson intermediate state. We estimate the coupling constant g(omega sigma gamma) utilizing the experimental value of the omega --> pi (0)pi (0)gamma decay rate.

The decay rho(0) -> pi(0)pi(0)gamma and the role of sigma-meson Gokalp, A; Yılmaz, Osman (2001-05-24) We study the radiative decay p(0) --> pi (0)pi (0)gamma within the framework of a phenomenological approach in which the contributions of sigma -meson and omega -meson intermediate states and of the pion-loops are considered. We conclude that the sigma -meson amplitude makes a substantial contribution.
Strong coupling constants of the octet baryons to Kand pi mesons in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ (2007-06-20) In this work, the strong coupling constants of the octet baryons to the K and pi mesons are studied within the Light Cone QCD sum rule method. It is well known that in the SU(3)(f) limit, these couplings can be expressed in terms of only 2 constants, so called F and D constants. In this work, the SU(3)(f) symmetry violating effects are also studied and it is shown that all the coupling constants can be expressed in terms of four analytical functions of the quark parameters.
Strong Coupling Constants of Heavy Baryons With Light Mesons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (2012-06-21) The strong coupling constants of the heavy spin-1/2 and spin-3/2 baryons with light pseudoscalar and vector mesons are calculated in the framework of the light cone QCD sum rules. Using the symmetry arguments, some structure independent relations among different correlation functions are obtained. It is shown that all possible transitions are described by only one invariant function, whose explicit expression is structure dependent.
The Sigma(0)Lambda transition magnetic moment in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2001-09-20) Using the general form of the Sigma (0) and Lambda currents, the Sigma (0)Lambda transition magnetic moment is calculated in framework of the light cone QCD sum rules. A comparison of our result on this quantity with the existing theoretical results and experimental data is presented.
Extended dynamical symmetries of Landau levels in higher dimensions Kürkcüoğlu, Seçkin; YURDUŞEN, İSMET (Springer Science and Business Media LLC, 2020-02-14) Continuum models for time-reversal (TR) invariant topological insulators (Tis) in d >= 3 dimensions are provided by harmonic oscillators coupled to certain SO(d) gauge fields. These models are equivalent to the presence of spin-orbit (SO) interaction in the oscillator Hamiltonians at a critical coupling strength (equivalent to the harmonic oscillator frequency) and leads to flat Landau Level (LL) spectra and therefore to infinite degeneracy of either the positive or the negative helicity states depending on...
