Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s=7TeV
(American Physical Society, 2012-10)
A search for physics beyond the standard model is performed in events with at least three jets and large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of √s=7TeV. No significant ...
Observation of sequential Υ suppression in PbPb collisions
(American Physical Society, 2012-11)
The suppression of the individual Υ(nS) states in PbPb collisions with respect to their yields in pp data has been measured. The PbPb and pp data sets used in the analysis correspond to integrated luminosities of 150μb -1 ...
