Abstract
A search for contact interactions has been performed using dimuon events recorded with the ATLAS detector in proton-proton collisions at [sqrt]s=7  TeV. The data sample corresponds to an integrated luminosity of 42  pb[superscript] -1. No significant deviation from the standard model is observed in the dimuon mass spectrum, allowing the following 95% C.L. limits to be set on the energy scale of contact interactions: Λ>4.9  TeV (4.5 TeV) for constructive (destructive) interference in the left-left isoscalar compositeness model. These limits are the most stringent to date for mumuqq contact interactions.
