In the late nineties several authors suggested that the extra dimensions predicted by string theory might lead to observable effects at high energy colliders. The ATLAS experiment which will start taking data at the LHC in 2007 will be an excellent place to search for such effects. A large set of models within the ADD or the Randall Sundrum geometries has been studied in ATLAS. These models predict a variety of signatures: jets and missing energy from direct graviton production, high mass tails in dilepton and diphoton production due to virtual graviton exchange, production of Kaluza-Klein excitations of standard model particles, etc. The sensitivity of ATLAS to these signatures will be presented. |
