Abstract:
This paper presents the first direct measurement of the B meson differential cross section dσ/dpT in pp̄ 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. © 1995 The American Physical Society.
