Measurements of jet multiplicity and differential production cross sections of Z+jets events in proton-proton collisions at √s =7TeV
(2015)Physical Review DMeasurements of differential cross sections are presented for the production of a Z boson and at least one hadronic jet in proton-proton collisions at √s = 7 TeV, recorded by the CMS detector, using a data sample corresponding to an integrated luminosity of 4.9 fb⁻¹. The jet multiplicity distribution is measured for up to six jets. The differential cross sections are measured as a function of jet transverse momentum and pseudorapidity ...Journal Article -
Comparison of the Z/γ∗ + jets to γ + jets cross sections in pp collisions at √s = 8 TeV
(2015)Journal of High Energy PhysicsA comparison of the differential cross sections for the processes Z/γ * + jets and photon (γ)+jets is presented. The measurements are based on data collected with the CMS detector at s√=8 TeV corresponding to an integrated luminosity of 19.7 fb−1. The differential cross sections and their ratios are presented as functions of p T. The measurements are also shown as functions of the jet multiplicity. Differential cross sections are obtained ...Journal Article
