Abstract:

We measure the neutral D total forward cross section and the differential cross sections as function of Feynman-x (

x_F

) and transverse momentum squared for 500 GeV/c

\pi^-

-nucleon interactions. The results are obtained from 88990+-460 reconstructed neutral D mesons from Fermilab experiment E791 using the decay channels

D\to K^-\pi^+

and

D\to K^-\pi^+\pi^-\pi^+

(and charge conjugates). We extract fit parameters from the differential cross sections and provide the first direct measurement of the turnover point in the

x_F

distribution, 0.0131+-0.0038. We measure an absolute

D^0 + \bar{D^0}

(

x_F > 0

) cross section of 15.4+1.8-2.3 microbarns/nucleon (assuming a linear A dependence). The differential and total forward cross sections are compared to theoretical predictions and to results of previous experiments.
