Περίληψη:
This paper presents results on charged Higgs boson production, based on
LEP data collected at root s = 172 GeV, that complement the previous
DELPHI results obtained at centre of mass energies up to 161 GeV. The
charged Higgs bosons are assumed to be pair produced and to decay either
into a quark pair or into tau nu(tau). The three different possible
final states are included in the analysis. Data from rings imaging
Cherenkov and microvertex detectors are used to identify the quarks as a
cs pair, The number of candidates found is compatible with the
background expected from standard processes. Combining the results of
the present analysis with those of the previous analysis at lower
energies, a new lower mass limit for the charged Higgs boson is set at
54.5 Gev/c(2). (C) 1998 Elsevier Science B.V.
