Improvement of the Global Tracking Trigger algorithm for the upgrades of the ZEUS detector at HERA

Objective

The electron-proton collider HERA at DESY in Hamburg operates at a center-of-mass energy of 318GeV and an instantaneous luminosity of 4*10^31cm^-2 s^-1. The ZEUS experiment is a multi-purpose detector, which has recently upgraded its tracking detectors.

A new silicon strip micro-vertex detector (MVD) precisely measures particle trajectories close to the interaction point and a Straw Tube Tracker (STT) measures forward going tracks down to polar angles of 5 degrees with respect to the incident protons. Together with the central tracking detector (CTD), these new components greatly improve the tracking capabilities of ZEUS. In order to fully exploit the new tracking detectors, the ZEUS second level trigger was upgraded with the addition of the Global Tracking Trigger (GTT), a PC farm which is interfaced to the data acquisition systems of the CTD, the STT, and the MVD.

This system reconstructs tracks and does vertexing on events, which fire the first level trigger (at about 300Hz). The scenario for a two-year project will be to spend the first year concentrating on developing triggering algorithms to improve the performance of the GTT, with the goal of triggering on the displaced vertices, which arise from the decay of long-lived particles such as hadrons containing charm or beauty quarks. The second year would be devoted to a leading role in a high-statistics physics analysis of heavy quark production (charm and beauty) in Deep Inelastic Scattering.

The analysis will require the development of offline tracking tools based on the enhanced information available from the new vertex and forward trackers, together with that from the CTD. The unambiguous identification of final state heavy quarks will allow detailed studies of the strong interaction dynamics involved in both their production and decay and will also allow a precise determination of the gluon content of the proton.
