“…Finally the possibility of single top quark production via squark and slepton exchanges to probe several combinations of R p couplings at hadron colliders has been studied in [547,548,549,550]. Initial state partons such as ud are particularly relevant for pp colliders such as the Tevatron while the ud initial state system is more relevant for pp colliders such as the LHC.…”

“…Assuming the observability criteria ∆σ/σ 0 > 20% where ∆σ is the R p cross-section and σ 0 is the Standard Model cross-section, Table 7.18 from [548] shows the sensitivities on λ LHC have been obtained in [549]. A more detailed simulation has been performed in [550] and the sensitivities on the coupling product λ [550]. Supersymmetric particle masses reconstruction have been also performed within the framework of single top production in [550].…”

Theoretical and phenomenological implications of R-parity violation in supersymmetric theories are discussed in the context of particle physics and cosmology. Fundamental aspects include the relation with continuous and discrete symmetries and the various allowed patterns of R-parity breaking. Recent developments on the generation of neutrino masses and mixings within different scenarios of R-parity violation are discussed. The possible contribution of Rparity-violating Yukawa couplings in processes involving virtual supersymmetric particles and the resulting constraints are reviewed. Finally, direct production of supersymmetric particles and their decays in the presence of R-parity-violating couplings is discussed together with a survey of existing constraints from collider experiments.To be submitted to Physics Reports

We present a new next-to-leading order calculation for fully differential single-topquark final states. The calculation is performed using phase space slicing and dipole subtraction methods. The results of the methods are found to be in agreement. The dipole subtraction method calculation retains the full spin dependence of the final state particles. We show a few numerical results to illustrate the utility and consistency of the resulting computer implementations.

Single slepton production in association with a top quark at the CERN Large Hadron Collider (LHC) is one of the important processes in probing the R-parity violation couplings. We calculate the QCD next-to-leading order (NLO) corrections to the pp → tl − (tl + ) + X process at the LHC and discuss the impacts of the QCD corrections on kinematic distributions. We investigate the dependence of the leading order (LO) and the NLO QCD corrected integrated cross section on the factorization/renormalization energy scale, slepton, stop-quark and gluino masses. We find that the uncertainty of the LO cross section due to the energy scale is obviously improved by the NLO QCD corrections, and the exclusive jet event selection scheme keeps the convergence of the perturbative series better than the inclusive scheme. The results show that the polarization asymmetry of the top-quark will be reduced by the NLO QCD corrections, and the QCD corrections generally increase with the increment of thet 1 org mass value.
