Query: NLO QCD corrections to WWbb production and top quark observables   We present the NLO QCD corrections to the production of a W+W- pair and two
b-jets, including the leptonic decays of the W bosons. Contributions from
singly resonant and non-resonant top quarks are fully taken into account. We
also discuss observables relevant for top quark mass measurements and top quark
asymmetries.
