h⁰→ W+W- ℓ+ℓ'⁻νℓ νℓ' as the Dominant SM Higgs Search Mode at the LHC for Mₕ₀= 155-180 GeV

الأصل · EN

We show that the Standard Model Higgs decay h⁰ → W+W - → l+ l- νν is the most sensitive mode for SM Higgs searches in the range 155-180 GeV. The previously considered mode h⁰ → Z⁰ Z⁰* → l+ l- l+l- has a significantly lower search sensitivity. We place particular emphasis on two new cuts based on (i) the boost and (ii) the spin-correlation of the W+W--system. The distribution we obtain from our combined cuts shows a mass sensitive peak which probably allows a mass determination to ± 5 GeV for 5 fb⁻¹. This contribution complements our earlier published paper.
