Graduate student Tülin Varol and Prof. Willocq have led an update to the search for contact interactions in the dilepton channel at the LHC. The new results have been submitted to the new Physical Review X online journal and the preprint can be seen at
http://arxiv.org/abs/1112.4462.  This new search  was carried out with about 1 fb^-1 of proton-proton collisions data, corresponding to a factor 25 increase in statistics over the previous results. The new search adds the dielectron channel to the dimuon channel and excludes the existence of contact interactions up to scales of about 10 TeV.

Tülin Varol presented those results at CERN on Dec 8 in the context of the “Implications of LHC results for TeV-scale physics” workshop, see her talk in the agenda.
