Search for low-scale gravity signatures in multi-jet final states with the ATLAS detector at √s = 8 TeV

A search for physics beyond the Standard Model in the multi-jet final state using 20.3 fb-1 of √s = 8 TeV pp collision data recorded using the ATLAS detector in 2012 is presented. No significant excess of events beyond SM predictions is observed. Upper limits on the visible cross section for non-SM production of multi-jet final states are placed at the 95% confidence level. Using a number of models of low-scale gravity, exclusion contours are drawn in the space of lower-mass threshold of production and fundamental Planck mass. These contours exclude the lower-mass production threshold for black hole and string ball production ranging from 4.6 to 6.2 TeV.
