Comments on the internal motion of massive charm quark in the process of double charmonium production in e+e- annihilations
Abstract
Description
The cross section value of doubly charmonium production in e+e- annihilations have been estimated at interaction energy 10.6 GeV. The quarkonium wave function shape, as well as the nonzero value of charm quark have been taken into account.
