Polarized J/psi production at CLEO
(1998)
关键词
摘要
Polarizations of the prompt $J/\psi#x27;s produced in the $e^+e^-$ annihilation
at CLEO energy ($\sqrt{s} = 10.58$ GeV) are considered in the framework of
NRQCD factorization formalism. We find that the $J/\psi$ polarization has
strong dependence on the production mechanism. At CLEO energy, the most
dominant $J/\psi$ production mechanism in ...更多
