Molecular interpretation of X(3960) as $$D_s^+ D_s^-$$ D s + D s - state
Abstract We study $$D_s^+ D_s^-$$ D s + D s - and $$D \bar{D}$$ D D ¯ states assuming that they are hadronic molecules with $$J^{PC}=0^{++}$$ J PC = 0 + + quantum number. We use two-point QCD sum rule formalism and extract the mass and decay constant values of these states. We take into account cont...
