Search for New Physics with Monojet plus missing transverse energy at CMS

TL;DR

This paper reports a search for new physics phenomena using monojet plus missing transverse energy events at the CMS detector, finding results consistent with the Standard Model and setting limits on extra-dimensional and unparticle models.

Contribution

First search for new physics in monojet plus missing energy channel at 7 TeV with CMS, constraining ADD and unparticle models.

Findings

Observed events agree with Standard Model predictions

Limits set on parameters of ADD model

Limits set on unparticle model parameters

Abstract

Results are presented for the search for new physics in the monojet plus missing transverse energy channel using pp collision data at a centre-of-mass energy of 7 TeV. The data were collected by the CMS detector at the LHC, and correspond to an integrated luminosity of 36 pb-1. The number of observed events is found to be in good agreement with Standard Model predictions and limits are placed on parameters in the framework of the ADD model and unparticles.
