Cross Sections

Integrated Cross Sections

Integrated D0D*- cross section vs ΔφThe D0D*- pair cross section as function of Δφ. The transverse momentum , pT, and pseudo rapidity, y,  ranges are given on the plot.

The measurements (points) are compared to the leading order matrix element plus parton shower event generator Pythia (Tune A ) (black line). Also shown are the contributions of the leading order production mechanisms flavor creation (red), flavor excitation (green) and gluon splitting (blue).

Integrated D+D*- cross section vs ΔφThe D+D*- pair cross section as function of Δφ The transverse momentum , pT, and pseudo rapidity, y,  ranges are given on the plot.

The measurements (points) are compared to the leading order matrix element plus parton shower event generator Pythia (Tune A ) (black line). Also shown are the contributions of the leading order production mechanisms flavor creation (red), flavor excitation (green) and gluon splitting (blue).

An additional plot of the D0D*- pair cross section with the same trigger side D pT range as for D+D*- pair cross section the is available in eps and gif format.
