1P1Charmonium Production at the Fermilab Tevatron

The production of the ${}_{}{}^1{}_{}{}^{}P_1^{}{}_{}{}^{}$ charmonium state $h_c$ at large $p_T$ at the Tevatron is considered. The color-octet contributions to this state are found to be dominant and give a reasonably large rate for the production of $h_c$. This should make it feasible to look for this resonance in the $J/\psi +\pi$ decay channel. This production rate is a prediction of nonrelativistic QCD (NRQCD), and the observation of the $h_c$ at the Tevatron can, therefore, be used as a test of the color-octet predictions of NRQCD.
