"New Experiments with Antiprotons"

ABSTRACT:

Fermilab operates the world's most intense antiproton source. Experiments have been proposed to use these antiprotons, either parasitically during Tevatron Collider running, or after the end of the Tevatron Collider program. For example, the annihiliation of 5 to 8 GeV antiprotons is expected to yield world-leading sensitivities to hyperon rare decays and CP violation. It could also provide the world's most intense source of tagged DO mesons, and thus the best near-term opportunity to study charm mixing and, via CP violation, to search for new physics. Other measurements that could be made include properties of the X (3872) and the charmonium system and unique antiproton Drell-Yan studies of nucleon structure. An experiment using a Penning trap and an atom interferometer could make the world's first measurement of the gravitational force on antimatter. The experiments are sufficiently cost-effective to be practical even in the tight-budget scenarios that are upon us/ They offer a great opportunity for a broad and exciting physics program at Fermilab in the post-Tevatron era.
