Description
We determine the mass of the top quark from cross section data for the hadro-production of single top quarks in the $t$- and $s$-channel reactions. We apply QCD perturbative corrections up to next-to-next-to-leading order terms from soft-gluon resummation to extract the top-quark mass in well-defined renormalization schemes. The cross section for the production of single top quarks is dominated by the light quark-flavor distributions in the proton, which allows for a mass determination largely independent of the gluon distribution.
