Higher-order soft-gluon corrections for tt¯Z cross sections

Higher-order soft-gluon corrections for tt¯Z cross sections

We calculate higher-order soft-gluon corrections for the associated production of a top-antitop quark pair and a Z boson (tt¯Z production) in proton-proton collisions. We find that these corrections are numerically dominant and large. We present approximate NNLO (aNNLO) and approximate N3LO (aN3LO)...
