Search for new physics in proton-proton collisions at 7 TeV in events with a single lepton, jets, and missing transverse momentum

Abstract

Changed:
<
<
Results are reported from a search for new physics beyond the Standard Model in proton-proton collisions at a center-of-mass energy = 7 TeV, focusing on the signature with a single isolated lepton, energetic jets, and large missing transverse momentum. The data sample comprises an integrated luminosity of 36.1 pb−1 recorded by the CMS experiment at the Large Hadron Collider. The presence of the lepton indicates an electroweak decay; the multiple jets can be produced in the complex decay chains of heavy objects; and the large missing momentum is associated with the presence of unobserved (weakly interacting) particles. The missing momentum can arise either from neutrino production, or, in models based on supersymmetry (SUSY), from production of the lightest supersymmetric particle. The observed number of events is consistent with Standard Model expectations based on data-driven background estimates using control samples. The results are interpreted in terms of constraints on SUSY parameter space.
