摘要
The detection of an intermediate mass charged Higgs boson at γγ colliders via the modes γγ→H + H - → ντ + ντ - , cscs, and ντ + cs+csντ - is considered. W + W - boson pair production is the dominant background for these modes. The three modes may be used in a complementary fashion to detect a charged Higgs boson. The mixed leptonic-hadronic mode may be used to determine the charged Higgs mass by reconstructing the invariant hadronic mass. The sensitivity of Br(H + →cs, ντ + ) on the discovery limit of the charged Higgs boson is also discussed. © 1993.
