Search for associated Higgs boson production using like charge dilepton events in p(p)over-bar collisions at sqrt(s)=1.96 TeV
2011
Abstract
We present a search for associated Higgs boson production in the process p (p) over bar -} W/ZH -} l(+/-)l''(+/-) + X in ee, e mu, and mu mu final states. The search is based on data collected by the D0 experiment at the Fermilab Tevatron Collider at sqrt(s) = 1.96 TeV corresponding to 5.3 fb(-1) of integrated luminosity.
We require two isolated leptons (electrons or muons) with the same electric charge and additional kinematic requirements. No significant excess above background is observed, and we set 95% C.
L. observed (expected) upper limits on ratio of the production cross section to the standard model prediction of 6.4 (7.3) for a Higgs boson mass of 165 GeV and 13.5 (19.8) for a mass of 115 GeV.
