A Search for the Standard Model Higgs Boson Produced in Association with a $$W$$ Boson
- Baylor Univ., Waco, TX (United States)
We present a search for a standard model Higgs boson produced in association with a W boson using data collected with the CDF II detector from p$$\bar{p}$$ collisions at √s = 1.96 TeV. The search is performed in the WH → ℓvb$$\bar{b}$$ channel. The two quarks usually fragment into two jets, but sometimes a third jet can be produced via gluon radiation, so we have increased the standard two-jet sample by including events that contain three jets. We reconstruct the Higgs boson using two or three jets depending on the kinematics of the event. We find an improvement in our search sensitivity using the larger sample together with this multijet reconstruction technique. Our data show no evidence of a Higgs boson, so we set 95% confidence level upper limits on the WH production rate. We set limits between 3.36 and 28.7 times the standard model prediction for Higgs boson masses ranging from 100 to 150 GeV/c2.
