Background to t-quark signals from higher-order QCD contributions

Journal Article · · Phys. Rev. D; (United States)
In pp-bar collider experiments, the higher-order QCD subprocesses qq-bar..-->..gQQ-bar, qg..-->..qQQ-bar, gg..-->..gQQ-bar (with Q = c,b) can lead to events with high-p/sub T/ leptons and apparently broad jets that may fake the usual signals of t-quark production and decay. We evaluate these contributions quantitatively, with plausible approximations, and conclude that the background they provide can be largely eliminated by suitable experimental selection criteria.
