| 英文摘要 | We evaluate the cross section for single slepton production at hadron colliders in supersymmetric theories with R-parity violating interactions to the next-to-leading order in QCD. We obtain fully differential cross section by using the phase space slicing lethod. We also perform soft-gluon resummation to all order in alpha(s) of leading logarithm to obtain a complete transverse momentum spectrum of the slepton. We find that the full transverse momentum spectrum is peaked at a few GeV, consistent with the early results for Drell-Yan production of lepton pairs. We also consider the contribution from gluon fusion via quark-triangle loop diagrams dominated by the b-quark loop. The cross section of this process is significantly smaller than that of the tree-level process induced by the initial b (b) over bar annihilation. |
