The q T and ∆ ϕ t t ¯ $$ \Delta {\phi}_{t\overline{t}} $$ spectra in top-antitop hadroproduction at NNLL+NNLO: the interplay of soft-collinear resummation and Coulomb singularities

The q T and ∆ ϕ t t ¯ $$ \Delta {\phi}_{t\overline{t}} $$ spectra in top-antitop hadroproduction at NNLL+NNLO: the interplay of soft-collinear resummation and Coulomb singularities

Abstract In this paper, we present the resummation-improved differential transverse momentum and azimuthal decorrelation cross sections, d σ t t ¯ / d q T $$ {\textrm{d}\sigma}_{t\overline{t}}/{\textrm{d}q}_{\textrm{T}} $$ and d σ t t ¯ / d ∆ ϕ t t ¯ $$ {\textrm{d}\sigma}_{t\overline{t}}/\textrm{d}\...
