The problem analyzed in this work is the calculation of the coupling of L = 1 axial-vector heavy quarkonia to vector and pseudo-scalar open flavor mesons. Calculations are based on light-cone QCD sum rules, with inputs from indepen- dently performed quark model calculations for the analysis of radially excited states. Those couplings are of interest for being inputs for effective theory calcu- lations on the quark content and transitions of axial-vector Xc/b mesons. Results involve profiles for the light-cone distribution amplitudes of charmonia and bot- tomonia, their respective leptonic decay constants and the mentioned coplings. Charmonium content of X(3872) is also discussed in light of the results.

Elliptic Flow of Charm and Strange Hadrons in High-Multiplicity p plus Pb Collisions at root(NN)-N-s=8.16 TeV Sirunyan, A. M.; et. al. (2018-08-01) The elliptic azimuthal anisotropy coefficient (upsilon(2)) is measured for charm (D-0) and strange (K-S(0), Lambda, Xi(-), and Omega(-)) hadrons, using a data sample of p + Pb collisions collected by the CMS experiment, at a nucleonnucleon center-of- mass energy of root(NN)-N-s = 8.16 TeV. A significant positive upsilon(2) signal from long- range azimuthal correlations is observed for all particle species in high- multiplicity p + Pb collisions. The measurement represents the first observation of possible l...
Radiative decays of the heavy tensor mesons in light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2019-01-11) The transition form factors of the radiative decays of the heavy tensor mesons to heavy pseudoscalar and heavy vector mesons are calculated in the framework of the light-cone QCD sum rules method at the point Q(2) = 0. Using the obtained values of the transition form factors at the point Q(2) = 0, the corresponding decay widths are estimated. The results show that the radiative decays of the heavy-light tensor mesons could potentially be measured in the future planned experiments at LHCb.
Magnetic moments of decuplet baryons in light cone QCD Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2000-09-01) We calculate the magnetic moments of decuplet baryons containing strange quarks within the framework of light cone QCD sum rules taking into account the SU(3) flavor symmetry breaking effects. It is obtained that magnetic moments of the neutral Sigma(*0) and Xi(*0) baryons are mainly determined by the SU(3) breaking terms. A comparison of our results on the magnetic moments of the decuplet baryons with the predictions of other approaches is presented.
EXACT BOUND STATES OF THE D-DIMENSIONAL KLEIN-GORDON EQUATION WITH EQUAL SCALAR AND VECTOR RING-SHAPED PSEUDOHARMONIC POTENTIAL IKHDAİR, SAMEER; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2008-09-01) We present the exact solution of the Klein Gordon equation in D-dimensions in the presence of the equal scalar and vector pseudoharmonic potential plus the ring-shaped potential using the Nikiforov-Uvarov method. We obtain the exact bound state energy levels and the corresponding eigen functions for a spin-zero particles. We also find that the solution for this ring-shaped pseudoharmonic potential can be reduced to the three-dimensional (3D) pseudoharmonic solution once the coupling constant of the angular ...
