Search for new particles in two-jet final states in 7 TeV proton-proton collisions with the ATLAS detector at the LHC

A search for new heavy particles manifested as resonances in two-jet final states is presented. The data were produced in 7 TeV proton-proton collisions by the LHC and correspond to an integrated luminosity of 315nb - 1 collected by the ATLAS detector. No resonances were observed.

Sumario:A search for new heavy particles manifested as resonances in two-jet final states is presented. The data were produced in 7 TeV proton-proton collisions by the LHC and correspond to an integrated luminosity of 315nb - 1 collected by the ATLAS detector. No resonances were observed. Upper limits were set on the product of cross section and signal acceptance for excited-quark (q * ) production as a function of q * mass. These exclude at the 95% C.L. the q * mass interval 0.30<mq * <1.26TeV, extending the reach of previous experiments. © 2010 CERN, for the ATLAS Collaboration.
