    (ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) Charm production in deep inelastic ep scattering was measured with the ZEUS detector using an integrated luminosity of 354 pb^sup -1^. Charm quarks were identified by reconstructing D ^sup ±^ mesons in the D ^sup ±^ arrow right K ^sup ^pi^sup ±^pi^sup ±^ decay channel. Lifetime information was used to reduce combinatorial background substantially. Differential cross sections were measured in the kinematic region 5 < Q ^sup 2^ < 1000 GeV^sup 2^, 0.02 < y < 0.7, 1.5 < p ^sub T^ (D ^sup ±^) < 15 GeV and |eta(D ^sup ±^)| < 1.6, where Q ^sup 2^ is the photon virtuality, y is the inelasticity, and p ^sub T^ (D ^sup ±^) and eta(D ^sup ±^) are the transverse momentum and the pseudorapidity of the D ^sup ±^ meson, respectively. Next-to-leading-order QCD predictions are compared to the data. The charm contribution, ..., to the proton structure-function F ^sub 2^ was extracted.
