LHC: Is SUSY dead? c. MSSM is about to be excluded considering WMAP, g-2 etc… Taikan Suehara, LCWS 11 @ Granada, 30 Sep. 2011 page 4

Is SUSY dead? • Sure, c. MSSM is almost dead, but… – c. MSSM is just a ‘sample model’ among much wider SUSY world – There are plenty of other SUSY models which are still consistent with LHC • For ILC, light sleptons/gauginos may be hopeless… – If colored sector is strongly connected to the weak sector (such as c. MSSM) – There are still plenty of SUSY models which gives substantially no connection between colored and weak sectors Is SUSY dead? No! Not at all. But anyway we have to investigate more models than Taikan c. MSSM… (esp. @ for. Granada, ILC)30 Sep. 2011 Suehara, LCWS 11 page 5

Battaglia Black: theory, Red: experiment (ILC), Blue: experiment (CLIC) ILC seems to need ‘other than c. MSSM’ models while CLIC is still not so anxious now.

Other than c. MSSM (1): GMSB Heavy gravitino (~ 1 Ge. V, stop stau) Very 2 light gravitino (~ 10 -4 e. V c. G mode) Very light gravitino (~ 1 e. V, stau < mm) K. Mawatari T. Moroi W. Yamaura Taikan Suehara, LCWS 11 @ Granada, 30 Sep. 2011 page 8

Other than c. MSSM (2): Little Higgs: quark and lepton sector is separated Top-partner production (S. Matsumoto) Lepton sector measurement (E. Kato) Taikan Suehara, LCWS 11 @ Granada, 30 Sep. 2011 page 9

CLIC progress F. Simon, squark mass J-J. Blaising, smuon mass P. Roloff, chargino mass Great progress towards CDR! M. Battaglia, Z’ sensitivity Taikan Suehara, LCWS 11 @ Granada, 30 Sep. 2011 page 10

Summary of ‘my point of view’ • There are plenty of BSM talks in spite of ‘depressive’ LHC results … partly because of the attractive force of Granada • Since c. MSSM is almost dead, we need wider variety of models, especially models with colored and weak sector separated for ILC. – Many models are actively being investigated • Impressive progress towards CLIC CDR – Similar to the time of Lo. I in ILC… • Higgs may be a first probe of Te. V new physics Many impressive results shown in the BSM session is omitted because of time constraint, and since it is@just my point view.
