Abstract:

In order to extend the tracking acceptance, to improve the primary and secondary vertex reconstruction and thus enhancing the tagging capabilities for short lived particles, the ZEUS experiment at the HERA Collider at DESY installed a silicon strip vertex detector. The barrel part of the detector is a 63 cm long cylinder with silicon sensors arranged around an elliptical beampipe. The forward part consists of four circular shaped disks. In total just over 200k channels are read out using 2.9 m² of silicon. In this report a detailed overview of the design and construction of the detector is given and the performance of the completed system is reviewed. © 2007 Elsevier B.V. All rights reserved.

Abstract:

Charm production in deep inelastic scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 82 pb-1. Charm has been tagged by reconstructing D*+, D0, D+ and D+s (+ c.c.) charm mesons. The charm hadrons were measured in the kinematic range pT (D* +,D 0,D+) > 3GeV, pT (D+s ) > 2GeV and |η(D)| < 1.6 for 1.5 < Q2 < 1000GeV2 and 0.02 < y < 0.7. The production cross sections were used to extract charm fragmentation ratios and the fraction of c quarks hadronising into a particular charm meson in the kinematic range considered. The cross sections were compared to the predictions of next-to-leading-order QCD, and extrapolated to the full kinematic region in pT (D) and η(D) in order to determine the open-charm contribution, Fcc2 (x,Q2), to the proton structure function F2. © SISSA 2007.
