SUSY - Limits Squark and gluino masses of ~ 1TeV 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 GeV LC. Fraction of undetected models with no sparticles kinematically accessible at LC as a function of LHC integrated luminosity. T. G. Rizzo, ALCPG11 40

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. Summary 47
