Nonstandard Higgs bosons

The authors considered the prospects for producing and detecting very massive (eg. 100 GeV - 1 TeV) nonstandard Higgs bosons at a high energy pp collider. By nonstandard Higgs bosons they mean the additional color-singlet spin-O particles that occur in most extensions of the minimal (i.e. one Higgs doublet) SU2 x U1 model. The authors' main conclusions are: (a) The physics of nonstandard neutral Higgs particles is likely to be very similar to that of the neutral scalar in the minimal model. (b) Massive charged Higgs bosons will probably (ie. for most models and most parameter ranges) be very difficult to produce or detect, especially if their dominant decay is into t b-bar. (c) The W+ZH-, W+W+H--, and ZH/sup O/H/sup O'/ vertices are especially interesting. (d) The identification of t and b quark jets, mass resolution for jet pairs, and lepton sign identification are extremely important. (e) More detailed studies of various production mechanisms and backgrounds would be very useful
