"Measurement of the ratio of differential cross sections σ(pp-bar→Z+b jet)/σ(pp-bar→Z+jet) in pp-bar collisions at s√=1.96  TeV." Physical Review D, 87(9):092010. http://www.dx.doi.org/10.1103/PhysRevD.87.092010.0556-2821https://hdl.handle.net/1808/15681This is the publisher's version, also available electronically from http://journals.aps.org/prd/abstract/10.1103/PhysRevD.87.092010.We measure the ratio of cross sections, σ(pp-bar→Z+b jet)/σ(pp-bar→Z+jet), for associated production of a Z boson with at least one jet. The ratio is also measured as a function of the Z boson transverse momentum, jet transverse momentum, jet pseudorapidity, and the azimuthal angle between the Z boson with respect to the highest p(T) b tagged jet. These measurements use data collected by the D0 experiment in Run II of Fermilab’s Tevatron pp-bar Collider at a center-of-mass energy of 1.96 TeV, and correspond to an integrated luminosity of 9.7  fb(−1). The results are compared to predictions from next-to-leading order calculations and various Monte Carlo event generators.Article10.1103/PhysRevD.87.092010openAccess
