This paper presents the first direct measurement of the B meson differential cross section d/dpT in pp collisions at s=1.8 TeV using a sample of 19.30.7 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/K+ and B0J/K*0892, where J/+- and K*0K+-. A comparison is made to the theoretical QCD prediction calculated at next-to-leading order. 1995 The American Physical Society.
