SUSY - Limits Squark and gluino masses of ~ 1 Te. V can be excluded. 38

SUSY 39

SUSY Better LHC SUSY exclusion limits imply that SUSY particles will be less likely to be kinematically accessible at a 500 Ge. V LC. T. G. Rizzo, ALCPG 11 Fraction of undetected models with no sparticles kinematically accessible at LC as a function of LHC integrated luminosity. 40

Summary The LHC accelerator and CMS are working very well Measurements have shown that SM predictions for known physics have been essentially spot on There are no indications yet of new physics though the LHC experiments are now exploring new territory almost across the board. A long physics programme lies ahead as well as very exciting times. 47

Heavy Ion • CMS experiment performed flawlessly during the 2010 heavy ion run period at LHC • CMS has obtained significant statistics of hard probes • CMS conducted detailed measurements of global properties of medium in Pb. Pb and pp collisions • Our measurements indicate consistent view of the hot and dense medium – – Strong collective effects in the medium No quenching of weakly and electromagnetically interacting probes Strong quenching of partons, including b-quarks Suppression of quarkonia, including excited states of the
