Search for massive colored scalars in four-jet final states in root s=7 TeV proton-proton collisions with the ATLAS detector

Search for massive colored scalars in four-jet final states in root s=7 TeV proton-proton collisions with the ATLAS detector

A search for pair-produced scalar particles decaying to a four-jet final state is presented. The analysis is performed using an integrated luminosity of 34 pb(-1) recorded by the ATLAS detector in 2010. No deviation from the Standard Model is observed. For a scalar mass of 100 GeV (190 GeV) the limi...
