Details of Analyses
 jet search
: ATLAS 8TeV 5.8/fb
 2-6 hard jets + no lepton +
[CONF-2012-109]
 Original bound :
 3-lep search
 Exact 3 leptons +
: ATLAS 8TeV 13.0/fb
+ SM-like signal vetoes
[CONF-2012-154]
(no b-jets, no lepton pairs near MZ, etc…)
 Degenerated regions
are not excluded.

Prospects

14TeV, 300/fb
3000/fb
But here
gluino is required.
25 /28
… No constraint yet.
(large SM BKG)
is hopeful.
(less SM BKG)
… We need
Linear Collider?
