Measurement of D{plus-minus} and D{sup 0} production in deep Inelastic scattering using a lifetime tag at HERA.
The production of D{sup {+-}}- and D{sup 0}-mesons has been measured with the ZEUS detector at HERA using an integrated luminosity of 133.6 pb{sup -1}. The measurements cover the kinematic range 5 < Q{sup 2} < 1000 GeV{sup 2}, 0.02 < y < 0.7, 1.5 < p T{sup D} < 15 GeV and |{eta}{sup D}| < 1.6. Combinatorial background to the D-meson signals is reduced by using the ZEUS microvertex detector to reconstruct displaced secondary vertices. Production cross sections are compared with the predictions of next-to-leading-order QCD, which is found to describe the data well. Measurements are extrapolated to the full kinematic phase space in order to obtain the open-charm contribution, F{sub 2}{sup c{bar c}} to the proton structure function, F{sub 2}.
