Search for new physics in events with same-sign dileptons and b jets in pp collisions at sqrt(s) = 8 TeV

TL;DR

This study searches for signs of new physics in proton-proton collision events with same-sign dileptons and b jets at 8 TeV, setting limits on non-standard-model contributions.

Contribution

It provides the first constraints on new physics models using same-sign dilepton and b jet events at 8 TeV with detailed acceptance and efficiency data.

Findings

No excess above the standard model background was observed.

Upper limits were set on non-standard-model event contributions.

Results can be used to test a broad range of new physics models.

Abstract

A search for new physics is performed using events with isolated same-sign leptons and at least two bottom-quark jets in the final state. Results are based on a sample of proton-proton collisions collected at a center-of-mass energy of 8 TeV with the CMS detector and corresponding to an integrated luminosity of 10.5 inverse femtobarns. No excess above the standard model background is observed. Upper limits are set on the number of events from non-standard-model sources and are used to constrain a number of new physics models. Information on acceptance and efficiencies is also provided so that the results can be used to confront an even broader class of new physics models.
