Charm2000: A >10^8-charm experiment for the turn of the millennium

TL;DR

Charm2000 is a proposed fixed-target experiment capable of reconstructing over 10^8 charm decays, vastly surpassing current samples, and aims to explore charm physics, CP violation, and potential new physics beyond the Standard Model.

Contribution

It introduces a large-scale charm experiment with unprecedented data volume, enhancing the sensitivity to rare processes and new physics in charm decays.

Findings

Potential to observe direct CP violation at Standard Model levels

Significant sensitivity to flavor-changing neutral currents

Capability to study charm spectroscopy and lifetimes

Abstract

I discuss the physics reach of a fixed-target charm experiment which can reconstruct >10^8 charm decays, three orders of magnitude beyond the largest extant sample. Such an experiment may run at Fermilab shortly after the Year 2000. In addition to "programmatic" charm physics such as spectroscopy, lifetimes, and tests of QCD, this "Charm2000" experiment will have significant sensitivity to new physics in the areas of CP violation, flavor-changing neutral-current and lepton-number-violating decays, and mixing, and could observe direct CP violation in Cabibbo-suppressed decays at the level predicted by the Standard Model.
