摘要：

A measurement of the r polarization at hadron colliders offers an excellent signal for the detection of charged Higgs bosons, via the decay H +/- --> tau +/- v. We show how such a determination can distinguish these events from the W +/- --> tau +/- v background, for each of the tau --> pi-nu, rho-nu, a(l)nu, and l-nu-nu-BAR decay channels.
