An update of the search for production of micro black hole states at the LHC, the focus of research efforts of Prof. Dallapiccola, postdoc Dan Ventura and graduate students German Colon and Nathan Bernard, has been published in the Journal of High Energy Physics: arxiv.org/abs/1405.4254. The 2012 data were scrutinized for telltale signs of black hole evaporation via Hawking radiation.  No evidence of a signal was present, and thus lower limits were placed, in the context of models of extra spatial dimensions, on the fundamental energy scale of gravity, M_D, and the energy threshold above which semi-classical black hole states could be produced, M_th.  Based on 20.3 fb^-1 of integrated luminosity collected in proton-proton collisions with the ATLAS detector, values of M_th < 4.8-6.2 TeV have been ruled out at 95% confidence level.  These new results place the most stringent constraints to date on models proposing large, compactified extra dimensions.
