Resumen:
A search for the Standard Model Higgs boson in the decay channel H→ZZ(⁎)→ℓ+ℓ−ℓ′+ℓ′−, where ℓ=e,μℓ=e,μ, is presented. Protonproton collision data at s=7 TeV recorded with the ATLAS detector and corresponding to an average integrated luminosity of 2.1 fb−12.1 fb−1
are compared to the Standard Model expectations. Upper limits on the
production cross section of a Standard Model Higgs boson with a mass
between 110 and 600 GeV600 GeV
are derived. The observed (expected) 95% confidence level upper limit
on the production cross section for a Higgs boson with a mass of 194
GeV, the region with the best expected sensitivity for this search, is
0.99 (1.01) times the Standard Model prediction. The Standard Model
Higgs boson is excluded at 95% confidence level in the mass ranges
191197, 199200 and 214224 GeV.
