New molecular candidates: X(1910), X(2200), and X(2350)

Assuming the newly observed resonant structures X(1910), X(2200), and X(2350) as omega omega, omega phi, and phi phi molecular states, respectively, we compute their mass values in the framework of QCD sum rules. The numerical results are 1.97 +/- 0.17 GeV for omega omega state, 2.07 +/- 0.21 GeV for omega phi state, and 2.18 +/- 0.29 GeV for phi phi state, which coincide with the experimental values of X(1910), X(2200), and X(2350), respectively. This supports the statement that X(1910), X(2200), and X(2350) could be omega omega, omega phi, and phi phi molecular candidates, respectively. 10.1103/PhysRevD.86.116006
