Searches for effects of TeV-scale gravity in the 2010 ATLAS data

Models of extra dimensions give the solution of the hierarchy problem in the Standard Model by introducing the fundamental Planck scale in (n+4)-dimensions, where n is the number of extra dimensions, which is much smaller than the Planck scale in four space-time dimensions. Mini black holes and ADD graviton are new phenomena come from these models. Four kinds of searches for such new phenomena using the data collected in 2010 with the ATLAS detector at the LHC are presented. In these searches, the ADD model, which introduce large flat extra dimensions, is considered.
