Abstract
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 315 nb␣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 (q0) production as a function of q0 mass. These exclude at the 95% C.L. the q0 mass interval 0:30 < mq0 < 1:26 TeV, extending the reach of previous experiments.File in questo prodotto:
