Özet:

In this work, hadronic properties of exotic meson candidate Y (3940) and its orthogonal state are studied. These meson states are considered as a mixture of charmonium ( c0) and meson molecule. The interpolating quark currents for c0 and D D are used to construct the correlation function. QCD sum rules approach for two-point function is then used to derive OPE and phenomenological representation of the correlation function of these mesons. Next, these two representations are connected by the analytical continuity in the complex plane and the sum rules for the mass and the mixing angle are derived. Using these sum rules, properties of charmonium states are studied.
