The latest search for contact interactions and large extra dimensions with dielectrons and dimuons is now published in Phys. Rev. D, seeĀ http://prd.aps.org/abstract/PRD/v87/i1/e015010. The data sample corresponds to about 5 inverse femtobarns of proton-proton collisions collected by the ATLAS detector in 2011. Prof. Willocq and Graduate Student Varol have led the analysis of the dimuon channel.
