Correct definition of color singlet P-wave non-perturbative matrix element of heavy quarkonium production

Abstract Recently we have proved factorization of infrared divergences in NRQCD S-wave heavy quarkonium production at high energy colliders at all orders in coupling constant. One of the problem which still exists in the higher order pQCD calculation of color singlet P-wave heavy quarkonium producti...
