Measurement of the B Meson Differential Cross Section dσ/dpT in pp¯ Collisions at √s = 1.8 TeV
Abstract
This paper presents the first direct measurement of the B meson differential cross section dσ/dpT in pp¯ collisions at s = 1.8 TeV using a sample of 19.3+/-0.7 pb-1 accumulated by the Collider Detector at Fermilab. The cross section is measured in the central rapidity region \|y\|<1 for pTB>6.0 GeV /c by fully reconstructing the B meson decays B+-->J/ψK+ and B0-->J/ψK*0892, where J/ψ-->μ+μ- and K*0-->K+π-. A comparison is made to the theoretical QCD prediction calculated at next-to-leading order.
