Charged-Higgs- and R-parity violating slepton-strahlung at hadron colliders - art. no. 115011

It is shown that the radiation of a charged Higgs boson off a third-generat ion quark (charged-Higgs-strahlung) provides an important channel for the d iscovery of the charged Higgs boson at hadron colliders. Equivalently, in s upersymmetric models with explicit lepton-number (R-parity) violation, slep tons may also be produced in association with quarks (slepton-strahlung). H iggs- and slepton-strahlung production cross sections are given for both th e Fermilab Tevatron and the CERN Large Hadron Collider (LHC). The LHC cross sections imply that heavy O(TeV) charged Higgs bosons Can be produced via charged-Higgs-strahlung and that strahlung production of charged sleptons i s possible even for small R-parity violating couplings. The possible discov ery of sleptons through this channel offers a surprising handle on models o f neutrino masses. [S0556-2821(99)03821-7].
