LONG-LIVED CHARGED SUPERPARTICLES AT LHC

• Long-lived charged superpartners at LHC
• In the co-annihilation region of the CMSSM
  t-sleptons
  are long-lived and decay with a
  considerable delay.
• The existence of long-lived t-squarks is also
  possible,
  however, it requires very large
  negative values of
  trilinear soft
  supersymmetry breaking parameter A.
• In the focus point region
  
  of the CMSSM there exist
  
  long-lived
  charginos.
• Production x-sections at
  
  LHC quite large
