Abstract

This paper presents the first direct measurement of the

B

meson differential cross section

d σ {/ d p}_{T}

in

p \bar{p}

collisions at

\sqrt{s} = 1.8

TeV using a sample of

19.3 \pm 0.7

p

b^{- 1}

accumulated by the Collider Detector at Fermilab. 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^{+} \to J / ψ K^{+}

and

B^{0} \to J / ψ K^{* 0} (892)

, where

J / ψ \to μ^{+} μ^{-}

and

K^{* 0} \to K^{+} π^{-}

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