The $q_{\mathrm{T}}$ and $\hat{I}”\ddot{I}{•}_{t\bar{t}}$ spectra in top-antitop hadroproduction at NNLL+NNLO: the interplay of soft-collinear resummation and Coulomb singularities

Wan-Li Ju, Marek Schoenherr

In this paper, we present the resummation-improved differential transverse momentum and azimuthal decorrelation cross sections, $d\ddot{I}{ƒ}_{t\bar{t}}/d{q}_{\mathrm{T}}$ and $dσ_{t\bar{t}}…
