Phys. J. C PY 2017 BP 794 EP 9pp VL 77 IS 11 DI 10.1140/epjc/s10052-017-5354-z LA English AB We present the calculation of the next-to-leading order QCD corrections for top-quark pair production in association with an additional jet at hadron colliders, using the modified minimal subtraction scheme to renormalize the top- quark mass. The results are compared to measurements at the Large Hadron Collider run I. In particular, we determine the top-quark running mass from a tit of the theoretical results presented here to the LHC data. ER
