Resumen:
A search for pair-produced massive coloured scalar
particles decaying to a four-jet final state is performed by the ATLAS
experiment at the LHC in protonproton collisions at . The analysed data
sample corresponds to an integrated luminosity of 4.6 fb(−1). No
deviation from the Standard Model is observed in the invariant mass
spectrum of the two-jet pairs. A limit on the scalar gluon pair
production cross section of 70 pb (10 pb) is obtained at the 95 %
confidence level for a scalar gluon mass of 150 GeV (350 GeV).
Interpreting these results as mass limits on scalar gluons, masses
ranging from 150 GeV to 287 GeV are excluded at the 95 % confidence
level.A search for pair-produced massive coloured scalar particles
