Searches for TeV-gravity signatures in final states with leptons and jets with the ATLAS detector at sqrts = 7 TeV

The production of high transverse momentum events containing charged leptons and jets has been measured, using 1 fb−1 of data recorded by the ATLAS detector in 2011 at sqrts = 7 TeV. No excess beyond Standard Model expectations is observed, and lower limits on effective cross sections are set. Using models for string ball and black hole production and decay, exclusion contours are determined as a function of mass threshold and the fundamental gravity scale.
