{ital R}-parity-violating supersymmetry (with a conserved baryon number {ital B}) provides a framework for particle physics with lepton-number- ({ital L}-) violating interactions. We examine in detail the structure of the most general {ital R}-parity-violating ({ital B}-conserving) model of low-energy supersymmetry. We analyze the mixing of Higgs bosons with sleptons and the mixing of charginos and neutralinos with charged leptons and neutrinos, respectively. Implications for neutrino and sneutrino masses and mixing and {ital CP}-conserving sneutrino phenomena are considered. {ital L}-violating low-energy supersymmetry can be probed at future colliders by studying the phenomenology of sneutrinos. Sneutrino-antisneutrino mass splittings and lifetime differences can provide new opportunities to probe lepton number violation at colliders. {copyright} {ital 1999} {ital The American Physical Society}
