First measurement of the Zμ+μZ\rightarrow \mu^+ \mu^- angular coefficients in the forward region of pppp collisions at s=13\sqrt{s}=13 TeV

Abstract

The first study of the angular distribution of μ+μ\mu^+ \mu^- pairs produced in the forward rapidity region via the Drell-Yan reaction ppγ/Z+Xl+l+Xpp \rightarrow \gamma^{*}/Z +X \rightarrow l^+ l^- + X is presented, using data collected with the LHCb detector at a centre-of-mass energy of 13TeV, corresponding to an integrated luminosity of 5.1 fb1\rm{fb}^{-1}. The coefficients of the five leading terms in the angular distribution are determined as a function of the dimuon transverse momentum and rapidity. The results are compared to various theoretical predictions of the ZZ-boson production mechanism and can also be used to probe transverse-momentum-dependent parton distributions within the proton
