The intermediate mass Higgs

The subgroup concentrated on two problems. The first was how to search for a standard neutral Higgs, H0, in the intermediate mass range, 2,m/sub t/< m/sub H/< 2m/sub W/. The only method not obviously swamped by background is H0 production in association with W+-, with H0→tt-bar and W→iotaν. However, this strategy puts great demands on the ability to identify t-quarks efficiently. The second problem addressed was the detectability of H0 in the mass range 200 to 400 GeV. The question of signal versus background for a fusion-produced H0 was reexamined. Heavy H0 production in association with a Z0 was also studied. The fusion process, with H0 decay to W+W- or Z0Z0, remains by far the most promising way to look for a heavy Higgs scalar
