Bounding the Higgs width at the LHC

Abstract

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.
