Abstract:

This paper presents the first direct measurement of the

B

meson differential cross section,

d\sigma/dp_T

, in

p\overline{p}

collisions at

\sqrt{s}=1.8

TeV using a sample of

19.3 \pm 0.7

pb

~{-1}

accumulated by the Collider Detector at Fermilab (CDF). The cross section is measured in the central rapidity region

|y| < 1

for

p_T(B) > 6.0

GeV/

c

by fully reconstructing the

B

meson decays

B~{+}\rightarrow J/\psi K~{+}

and

B~{0}\rightarrow J/\psi K~{*0}(892)

, where

J/\psi \rightarrow \mu~+\mu~-

and

K~{*0} \rightarrow K~+ \pi~-

. A comparison is made to the theoretical QCD prediction calculated at next-to-leading order.
