We study radiative decays of D-sJ(*)(2317) and D-sJ(2460) using light-cone QCD sum rules. In particular, we consider the decay modes D-sJ(*)(2317)-> D-s(*)gamma and D-sJ(2460)-> D-s((*))gamma,D-sJ(*)(2317)gamma and evaluate the hadronic parameters in the transition amplitudes analyzing correlation functions of scalar, pseudoscalar, vector, and axial-vector (c) over bars currents. In the case of D-sJ(*)(2317)-> D-s(*)gamma we also consider determinations based on two different correlation functions in heavy quark effective theory (HQET), in order to estimate the finite charm-quark mass effects. The mode D-sJ(2460)-> D-s gamma turns out to have the largest decay rate among the radiative D-sJ(2460) channels, as experimentally observed, a result thus favoring the interpretation of D-sJ states as ordinary (c) over bars mesons.

Radiative decays of the p-wave charmed heavy baryons
Alıyev, Tahmasıb; Savcı, Mustafa (Springer Science and Business Media LLC, 2019-05-23)
The radiative decays of the p-wave charmed heavy baryons to the ground state baryon states are studied in the framework of the light cone QCD sum rules method. Firstly, the transition form factors that describe these transitions are estimated and then, using these form factors, the corresponding decay widths are calculated. A comparison of our results for the decay widths with those predicted by the other approaches existing in the literature is performed.
Radiative decays of decuplet to octet baryons in light cone QCD
Alıyev, Tahmasıb; Özpineci, Altuğ (Elsevier BV, 2006-01-02)
The radiative decays of decuplet to octet baryons are analyzed within the light cone QCD sum rules framework. The electromagnetic transition form factors for these decays are calculated at q(2) = 0 up to twist-4 accuracy for photon wave functions and including first order strange quark mass corrections. A comparison of our results with predictions of lattice theory and existing experimental data is presented. (c) 2005 Published by Elsevier B.V.
Radiative rho(+)->pi(+)gamma decay in light cone QCD
Gokalp, A; Yılmaz, Osman (2001-10-01)
We investigate the radiative rho (+) --> pi (+)gamma decay in the framework of the light cone QCD sum rules. We estimate the coupling constant gp,, for this decay and using this value of the coupling constant, we calculate the decay width of the rho (+) --> pi (+)gamma decay. Our result is in good agreement with the experimental value.
Radiative decay of the X(3872) as a mixed molecule-charmonium state in effective field theory
Cincioglu, E.; Özpineci, Altuğ (Elsevier BV, 2019-10-10)
Assuming that X(3872) is a mixture between 2P charmonium and (D) over barD* molecular states with J(PC) = 1(++), an analysis of X(3872) radiative decays into J/psi gamma and psi(2S)gamma is presented. The modification of the radiative branching ratio due to possible constructive or destructive interferences between the meson-loop and the short-distance contact term, which is modeled by a charm quark loop, is shown. The model predictions are shown to be compatible with the experimentally determined ratio of ...
Radiative decays of negative parity heavy baryons in the framework of the light cone QCD sum rules
Agamaliev, A.K.; Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2017-2)
The transition form factors responsible for the radiative Sigma(Q) -> Lambda(Q)gamma and Xi(')(Q) -> Xi(Q)gamma So decays of the negative parity baryons are examined within light cone QCD sum rules. The decay widths of the radiative transitions are calculated using the obtained results of the form factors. A comparison of our predictions on decay widths with the corresponding widths of positive parity baryons is given.
