Study of Z boson plus jets events using variables sensitive to double-parton scattering in pp collisions at 13 TeV

Double-parton scattering is investigated using events with a Z boson and jets. The Z boson is reconstructed using only the dimuon channel. The measurements are performed with proton-proton collision data recorded by the CMS experiment at the LHC at \sqrt{s} =13 TeV, corresponding to an integrated luminosity of 35.9 fb^{-1}collected in the year 2016. Differential cross sections of Z + \geq1 jet and Z + \geq2 jets are measured with...
