Abstract

Direct production of the charmonium-like state X(3872)X(3872) in e+ee^+e^- collisions is considered in the framework of the vector meson dominance model. An order-of-magnitude estimate for the width Γ(Xe+e)\Gamma(X\to e^+e^-) is found to be \gtrsim0.03 eV. The same approach applied to the χc1\chi_{c1} charmonium decay predicts the corresponding width of the order 0.1 eV in agreement with earlier estimates. Experimental perspectives for the direct production of the 1++1^{++} charmonia in e+ee^+e^- collisions are briefly discussed.
