A Search For The Higgs Boson In H-->ZZ-->2l2n Mode

TL;DR

This paper reports a search for the Standard Model Higgs boson in the H-->ZZ-->2l2n decay channel using CMS data from 2010-2011, setting limits on its production without observing a significant excess.

Contribution

First search for Higgs in the H-->ZZ-->2l2n channel using CMS data at 7 TeV, providing new limits on Higgs production.

Findings

No excess observed in the ZZ transverse mass.

Limits set on Higgs production cross-section.

Constraints on models with a fourth fermion family.

Abstract

A search for the Standard Model Higgs boson in proton-proton collisions at a center-of-mass energy of 7 TeV is presented in the decay channel H-->ZZ-->2l2n. The search is conducted by the CMS experiment with data accumulated during the 2010 and part of the 2011 running periods of the LHC, for a total integrated luminosity of 1.1/fb. No excess is observed in the ZZ transverse mass. Limits are set on the production of the Higgs boson in the context of the Standard Model and in the presence of a sequential fourth family of fermions with high masses.
