Findings

Tevatron experiments are now competitive with dedicated machines.

Upgraded systems improved detection of charm and beauty hadrons.

Enhanced trigger strategies enabled better data collection for charm physics.

Abstract

The first period of the Tevatron Run II has been dominated by low-Pt physics. Both detectors, and their trigger/DAQ systems have been largely modified to exploit as much as possible the large wealth of charm and beauty hadrons produced by the machine, with improvements in the tracking system, magnetic field, specific triggers based on on-line track reconstruction. Thanks to these improvements, Tevatron experiments are competitive with dedicated machines, not only for heavier beauty states but also for charm, both in leptonic and hadronic decays.
