Bounding the Higgs width at the LHC

Understand

We present results for the Standard model description of the four-lepton production, mediated both by Higgs boson production and by other one-loop standard model processes.

• The description of four-lepton final states in MCFM v6.8 is reviewed, with special reference to the interference effects that can occur for identical species of leptons.
• We present results both for interference in the $l^+l^- l^- l^+$ and in the $l^-l^+ \nu_l \bar{\nu}_l$ final state.
• Prospects for further improvement in the theoretical description of four lepton production are also reviewed.
