The Impact of Intrinsic Motion of Partonsin Drell–Yan Production at NLO with the Parton Branching Method

Internal (Fermi) motion of partons inside hadrons has been studied analysing Drell–Yan pair production at next-to-leading order with the parton branching method which provides transverse momentum dependent parton densities covering wide region of parton transversal momentum. Also, the dependences of intrinsic motion of partons on centre of mass energy, $$\sqrt{s}$$ , and Drell–Yan pair invariant mass, $$m_{\textrm{DY}}$$ , are examined.
