Abstract
We report on measurements of differential cross sections dsigma/dp(T) for prompt charm meson production in p (p) over bar collisions at roots=1.96 TeV using 5.8+/-0.3 pb(-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\less than or equal to1 in four fully reconstructed decay modes: D-0-->K(-)pi(+), D*+-->D(0)pi(+), D+-->K(-)pi(+)pi(+), D-s(+)-->phipi(+), and their charge conjugates. The measured cross sections are compared to theoretical calculations.
