Περίληψη:
We report on a measurement of the D+ -meson production cross section as
a function of transverse momentum (p(T)) in proton-antiproton (p (p)
over bar) collisions at 1.96 TeV center-of-mass energy, using the full
data set collected by the Collider Detector at Fermilab in Tevatron Run
II and corresponding to 10 fb(-1) of integrated luminosity. We use
D-broken vertical bar -> K- pi(broken vertical bar) pi(broken vertical
bar) decays fully reconstructed in the central rapidity region broken
vertical bar y broken vertical bar < 1 with transverse momentum down to
1.5 GeV/c, a range previously unexplored in p<(p)over bar> collisions.
Inelastic p (p) over bar -scattering events are selected online using
minimally biasing requirements followed by an optimized offline
selection. The K- pi(+) pi(+) mass distribution is used to identify the
D+ signal, and the D+ transverse impact-parameter distribution is used
to separate prompt production, occurring directly in the hard-scattering
process, from secondary production from b-hadron decays. We obtain a
prompt D+ signal of 2950 candidates corresponding to a total cross
section sigma(D+), 1.5 < P-T < 14.5 GeV/c, vertical bar y vertical bar <
1) = 71.9 +/- 6.8 (stat) +/- 9.3 (syst) mu b.While the measured cross
sections are consistent with theoretical estimates in each p(T) bin, the
shape of the observed p(T) spectrum is softer than the expectation from
quantum chromodynamics. The results are unique in p<(p)over bar>
collisions and can improve the shape and uncertainties of future
predictions.
