Set 1 uses the evolution scale while Set 2 uses transverse momentum as an argument in <jats:inline-formula><jats:alternatives><jats:tex-math>$$\alpha _\mathrm {s}$$</jats:tex-math><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub> <mml:mi>α</mml:mi> <mml:mi>s</mml:mi> </mml:msub> </mml:math></jats:alternatives></jats:inline-formula>, and the above observation therefore confirms the importance of an appropriate soft-gluon coupling in angular ordered parton evolution. The total uncertainties of the predictions are dominated by the scale uncertainties of the matrix element, while the uncertainties coming from the PB-TMDs and the corresponding PB-TMD shower are very small.
