Searching for squarks and gluinos in 0-lepton channel with W Signal Regions at ATLAS experiment. — •Tomas Javurek and Zuzana Rurikova for the ATLAS collaboration — University of Freiburg
Data with the integrated lumminosity of 20.3−1fb have been collected and analyzed by ATLAS during successful operation of LHC (Large Hadron Collider) in 2011 and 2012. The SUSY group at ATLAS have been searching for deviation from Standard Model expectations and 0-lepton analysis have played a crucial role in this effort with its fourteen Signal Regions out of that two have been dedicated to boosted W bosons in final state. New techniques of reconstruction of W boson have been developed and studied during past year to make the 0-lepton boosted W Signal Regions more efficient. Detailed study of one of these techniques, called "reclustering", is introduced in this talk. The results from the latest publication of the ATLAS SUSY 0-lepton analysis are summarized as well.
