Search for supersymmetry in events with b-quark jets and missing transverse energy in pp collisions at 7 TeV

TL;DR

This paper reports a search for supersymmetric particles in proton-proton collisions at 7 TeV, focusing on events with b-quark jets and missing energy, finding results consistent with the standard model and setting constraints on new physics.

Contribution

First search for supersymmetry in events with b-quark jets and missing energy at 7 TeV using CMS data, constraining supersymmetric models with simplified spectra.

Findings

Observed data matches standard model predictions.

Set upper limits on supersymmetric particle production cross sections.

No evidence found for supersymmetry in the analyzed events.

Abstract

Results are presented from a search for physics beyond the standard model based on events with large missing transverse energy, at least three jets, and at least one, two, or three b-quark jets. The study is performed using a sample of proton-proton collision data collected at sqrt(s) = 7 TeV with the CMS detector at the LHC in 2011. The integrated luminosity of the sample is 4.98 inverse femtobarns. The observed number of events is found to be consistent with the standard model expectation, which is evaluated using control samples in the data. The results are used to constrain cross sections for the production of supersymmetric particles decaying to b-quark-enriched final states in the context of simplified model spectra.
