Özet:

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.
