Production of Charm, Charmonium, and Beauty in 800$\,$GeV Proton-Nucleon Collisions
Abstract
Description
Some recent results from the Fermilab fixed-target experiment E789 on production of charm, charmonium, and beauty are summarized and compared to model predictions. The data indicate that heavy-quark and quarkonium production are not yet entirely understood. The largest discrepancy concerns the rate of $ψ^\prime$ production, which is a factor $\approx$25 above expectations.
