Signatures of Spontaneous Breaking of R-Parity in Gluino Cascade Decays at LHC
We study the pattern of gluino cascade decays in a class of supersymmetric
models where R-parity is spontaneously broken. We give a detailed discussion of
the R-parity violating decays of the lightest neutralino, the second lightest
neutralino and the lightest chargino. The multi-lepton and same-sign dilepton
signal rates expected in these models are compared with those predicted in the
Minimal Supersymmetric Standard Model. We show that these rates can be
substantially enhanced in broken R-parity models.Comment: 23 pages, LaTex file, 9 eps figures include
