Intrinsic Charm of Vector Mesons: A Possible Solution of the "rho pi" Puzzle
Abstract
An outstanding mystery of charmonium physics is why the J/ decays prominently to pseudoscalar plus vector meson channels, such as J/ -> π and J/ -> K*K, whereas the '(2S) does not. We show that such decays of J/ and their suppression for '(2S) follow naturally from the existence of intrinsic charm |qbar q cbar c> Fock components of the light vector mesons.
