Abstract: (arXiv)

We present a measurement of the forward-backward asymmetry in the production of

B^{\pm}

mesons,

A_{\rm FB}(B^{\pm})

, using

B^{\pm} \rightarrow J/\psi K^{\pm}

decays in 10.4

{\rm fb}^{-1}

of

p\bar{p}

collisions at

\sqrt{s} = 1.96

TeV collected by the D0 experiment during Run II of the Tevatron collider. A nonzero asymmetry would indicate a preference for a particular flavor, i.e.,

b

quark or

\bar{b}

antiquark, to be produced in the direction of the proton beam. We extract

A_{\rm FB}(B^{\pm})

from a maximum likelihood fit to the difference between forward- and backward-produced

B^{\pm}

mesons. We measure an asymmetry consistent with zero:

A_{\rm FB}(B^{\pm})

= [

D0 defines a coordinate system with the z axis along the proton beam direction, the x axis pointing away from the Tevatron center, and the y axis pointing upwards. Pseudorapidity is defined as = - ln[tan(/2)], where is the laboratory frame polar angle. Angle is the azimuthal angle in the x-y plane
