Search for microscopic black holes in a like-sign dimuon final state using large track multiplicity with the ATLAS detector
Abstract
A search is presented for microscopic black holes in a like-sign dimuon final state in proton-proton collisions at s=8TeV. The data were collected with the ATLAS detector at the Large Hadron Collider in 2012 and correspond to an integrated luminosity of 20.3fb-1. Using a high track multiplicity requirement, 0.6±0.2 background events from Standard Model processes are predicted and none observed. This result is interpreted in the context of low-scale gravity models and 95% C.L. lower limits on microscopic black hole masses are set for different model assumptions.
