Search for strong gravity signatures in same-sign dimuon final states using the ATLAS detector at the LHC

TL;DR

This paper reports a search for microscopic black holes in same-sign dimuon events at the LHC, finding no evidence and setting limits on low scale gravity models.

Contribution

First search for microscopic black holes in same-sign dimuon final states at 7 TeV with ATLAS, establishing exclusion limits on low scale gravity.

Findings

Data are consistent with Standard Model predictions.

No evidence of microscopic black holes was observed.

Exclusion contours were derived for low scale gravity models.

Abstract

A search for microscopic black holes has been performed in a same-sign dimuon final state using 1.3 fb^-1 of proton-proton collision data collected with the ATLAS detector at a centre of mass energy of 7 TeV at the CERN Large Hadron Collider. The data are found to be consistent with the expectation from the Standard Model and the results are used to derive exclusion contours in the context of a low scale gravity model.
