We present theoretical results with soft-gluon corrections for two separate processes: (1) the production of a single top quark in association with a $W$ boson in the Standard Model; and (2) the production of a single top quark in association with a heavy $Z'$ boson in new physics models with or without anomalous couplings. We show that the higher-order corrections from soft-gluon emission are dominant for a wide range of collider energies. Results are shown for the total cross sections and top-quark transverse-momentum and rapidity distributions for $tW$ and $tZ'$ production at LHC and future collider energies up to 100 TeV. The uncertainties from scale dependence and parton distribution functions are also analyzed.
List of changes
We have added a reference to the NLO calculation and a brief description of how we have dealt with the removal of overlap with ttbar production.

I appreciate the fact that the treatment of ttbar overlap has been mentioned.
Still, I do consider that the importance attributed to soft-gluon corrections is exaggerated and spelled in a misleading way . This also reflects the comments by Referee 3.
I also stress that cases are known where predictions based on soft-gluon resummation fail to reproduce the exact higher-order results, see eg https://arxiv.org/pdf/1303.0693.pdf for some top-related studies.
This said I leave the final decision to the editor in charge.
