K. Ackerstaff et al., SEARCH FOR CHARGED HIGGS BOSONS IN E(-) COLLISIONS AT ROOT-S = 130-172 GEV()E(), Physics letters. Section B, 426(1-2), 1998, pp. 180-192
A search is described to detect charged Higgs bosons via the process e
(+)e --> H+H, using data collected by the OPAL detector at center-of-m
ass energies of 130-172 GeV with a total integrated luminosity of 25 p
b(-1) The decay channels are assumed to be H+--> qq and H+ tau(+)nu(ta
u). No evidence for charged Higgs boson production is observed. The lo
wer limit for its mass is determined to be 52 GeV at 95% confidence le
vel, independent of the H+-->tau(+) nu tau branching ratio. (C) 1998 P
