Abstract

We report on measurements of differential cross sections

d σ / d p_{T}

for prompt charm meson production in

p \bar{p}

collisions at

\sqrt{s} = 1.96 T e V

using

5.8 \pm 0.3 {p b}^{- 1}

of data from the CDF II detector at the Fermilab Tevatron. The data are collected with a new trigger that is sensitive to the long lifetime of hadrons containing heavy flavor. The charm meson cross sections are measured in the central rapidity region

| y | \leq 1

in four fully reconstructed decay modes:

D^{0} \to K^{-} π^{+}

D^{* +} \to D^{0} π^{+}

D^{+} \to K^{-} π^{+} π^{+}

D_{s}^{+} \to φ π^{+}

, and their charge conjugates. The measured cross sections are compared to theoretical calculations.
