New Flavor Production in gamma , mu , nu , and Hadron BEAMS

摘要

During the last few years the main emphasis in the study of heavy particle production (mainly charm) by means other than e exp + e exp - annihilation has been on the production mechanisms. This review concentrates mainly on the production data in gamma , mu , nu , and hadron beams. The heavy flavor searches divide themselves naturally into three categories, each one characterized by its own peculiar advantages and shortcomings; these are summarized briefly. Then the following topics are taken up: charm production by hadrons (central production, forward production - lambda /sub c/ and D production, anomalies and discrepancies), charm production by photons and muons, new flavor production by neutrinos, status of heavier flavors, and production bound flavors (eta/sub c/ search, UPSILON muoproduction, J/psi and UPSILON hadroproduction, J/psi muoproduction). In his outlook for the future, the author presents a few words concerning the status of detectors: emulsions, high-resolution streamer chambers, high-resolution bubble chambers, and solid-state detectors. 83 references, 36 figures, 4 tables.
