We present the results of a search for standard model Higgs boson production with decay to WW(*), identified through the leptonic final states e(+)e(-)(nu) over bar nu,e(+/-)mu(-/+)(nu) over bar nu and mu(+)mu(-)(nu) over bar nu. This search uses 360 pb(-1) of data collected from p (p) over bar collisions at root s=1.96 TeV by the upgraded Collider Detector at Fermilab (CDF II).

Abstract

We present the results of a search for standard model Higgs boson production with decay to WW(*), identified through the leptonic final states e(+)e(-)(nu) over bar nu,e(+/-)mu(-/+)(nu) over bar nu and mu(+)mu(-)(nu) over bar nu. This search uses 360 pb(-1) of data collected from p (p) over bar collisions at root s=1.96 TeV by the upgraded Collider Detector at Fermilab (CDF II). We observe no signal excess and set 95% confidence level upper limits on the production cross section times branching ratio for the Higgs boson to WW(*) or any new scalar particle with similar decay products. These upper limits range from 5.5 to 3.2 pb for Higgs boson masses between 120 and 200 GeV/c(2).
