If R parity is not conserved, the lightest supersymmetric particle could decay via lepton-number-violating or baryon-number-violating interactions. The latter case is particularly insidious since it leads to a reduction of the E/{sub T} as well as leptonic signals for supersymmetry. We evaluate cross sections for jets plus E/{sub T}, 1scr(l), 2scr(l) (same sign and opposite sign), and 3scr(l) event topologies that result from the simultaneous production of all sparticles at the CERN Large Hadron Collider (LHC), assuming that the lightest supersymmetric particle {tilde Z}{sub 1} decays hadronically inside the detector via R-parity-violating interactions. We assume that these interactions do not affect the production rates or decays of other sparticles. We examine the SUSY reach of the LHC for this {open_quotes}pessimistic{close_quotes} scenario, and show that experiments at the LHC will still be able to search for gluinos and squarks as heavy as 1 TeV, given just 10 fb{sup {minus}1} of integrated luminosity, even with cuts designed to explore the canonical SUSY framework with a {ital conserved} R parity. {copyright} {ital 1997} {ital The American Physical Society}
