Abstract

We use NRQCD to predict the cross section for η_c production at the Tevatron. The non-perturbative matrix elements required are obtained, using heavy-quark symmetry, from the matrix elements determined from the CDF J/ψ data. Our numbers are, therefore, predictions of NRQCD and provide a very good test of it. Even after taking into account the small branching ratio of the η_c into two photons, a substantial rate for the production of this resonance at the Tevatron is expected.
