PY - 2014 DA - 2014// TI - Search for microscopic black holes and string balls in final states with leptons and jets with the ATLAS detector at root s=8 TeV T2 - J. High Energy Phys. JO - Journal of High Energy Physics SP - 103 EP - 48pp VL - 08 IS - 8 PB - Springer KW - Hadron-Hadron Scattering AB - A search for an excess of events with multiple high transverse momentum objects including charged leptons and jets is presented, using 20.3 fb(-1) of proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider in 2012 at a centre-of-mass energy of root s = 8 TeV. No excess of events beyond Standard Model expectations is observed. Using extra-dimensional models for black hole and string ball production and decay, exclusion contours are determined as a function of the mass threshold for production and the fundamental gravity scale for two, four and six extra dimensions. For six extra dimensions, mass thresholds of 4.8-6.2 TeV are excluded at 95 % confidence level, depending on the fundamental gravity scale and model assumptions. Upper limits on the fiducial cross-sections for non-Standard Model production of these final states are set.
