Polarization characteristics of photons produced in inclusive and semi-inclusive radiative decays of B mesons, B --> gamma + X-s, B --> gamma + h + X', are described in a general model-independent framework, using the structure function formalism.

General analysis of the polarization effects in N+N -> d+P processes
Yalcin, C; Rekalo, MP; Koru, H (IOP Publishing, 1998-05-01)
We establish the spin structure of matrix elements for N + N --> d + P processes, where P is a pi- or eta-meson, in terms of six scalar amplitudes. Isospin invariance of a strong interaction results in definite symmetry properties of these amplitudes relative to the change cos theta --> -cos theta; where theta is the P-meson production angle. We parametrize all possible polarization observables in n + p --> d + P using a formalism of structure functions and calculate these structure functions in terms of sc...
Sigma(Q)Lambda(Q)pi coupling constant in light cone QCD sum rules
Azizi, K.; Bayar, M.; Özpineci, Altuğ (American Physical Society (APS), 2009-03-01)
The strong coupling constants g(Sigma Q)Lambda(Q)pi (Q=b and c) are studied in the framework of the light cone QCD sum rules using the most general form of the baryonic currents. The predicted coupling constants are used to estimate the decay widths for the Sigma(Q)->Lambda(Q)pi decays which are compared with the predictions of the other approaches and existing experimental data.
The gV sigma gamma coupling constants in hadron electrodynamics
Rekalo, MP; Tomasi-Gustafsson, E (Elsevier BV, 2003-09-22)
Recent measurements of the branching ratios for the decays omega --> pi(0) pi(0)gamma and rho(0) --> pi(0)pi(0)gamma lead to coupling constants of the Vsigmagamma interaction (V is a vector meson) one order of magnitude smaller than previously assumed to describe the threshold cross section of gamma + p --> p + rho(0) and the HERMES effect. The new g(Vsigmagamma)(2) a couplings are in contradiction with the predictions of the QCD sum rules, but are in agreement with vector meson dominance estimation of the ...
Analysis of gamma(*) Lambda -> Sigma(0) transition in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2013-05-20)
The gamma(*) Lambda -> Sigma(0) transition form factors are investigated within the light- cone QCD sum rules method. Using the most general form of the interpolating current of Sigma(0) baryon and the distribution amplitudes of baryon we calculate the Q(2) dependence of the electromagnetic form factors. Our results are compared with the predictions of the covariant spectator quark model.
Determination of the g(V sigma gamma) coupling constant through theprocess gamma plus N -> N plus V with circularly polarized photons
Rekalo, MP; Tomasi-Gustafsson, E (Elsevier BV, 2003-02-24)
We suggest to measure the t-dependence of the two possible T-even asymmetries for the photoproduction of vector mesons, gamma + rho --> rho + V-0, V-0 = rho or omega, in the collision of circularly polarized photons with a polarized proton target. In the framework of a (pi + sigma)-model, these asymmetries are very sensitive to the relative role of pi- and sigma-exchanges, in the near threshold region.
