Cross section for forward [Formula Presented] production in [Formula Presented] collisions at [Formula Presented]

The inclusive cross section for [Formula Presented] production times the branching ratio [Formula Presented] has been measured in the forward pseudorapidity region: [Formula Presented] The results are based on [Formula Presented] of data collected by the CDF Collaboration at the Fermilab Tevatron Collider. The measurements extend earlier measurements of the D0 Collaboration to higher [Formula Presented] In the kinematic range where the experiments partially overlap, these data are in good agreement with previous measurements. © 2002 The American Physical Society.
