R parity violation

• Usual assumption: decay chain as in mSUGRA but LSP decays via B or L violating operator (hence no missing ET)

  • LEP sensitivity comparable to mSUGRA with R conserved
  • CDF and DØ searches for ee + jets; again, comparable sensitivity

• R violation in production process:

  • HERA “leptoquark” searches ep ? squark
  • LEP e+e- ? sneutrino ? tau pairs
