The center of the upgraded CDF detector features a silicon vertex detector, installed in January 2001. The improved detector has taken data since March 2001. The vertex detector allows experimenters to record tracks of charged particles with utmost precision. Tracing the particle tracks back to their origin, scientists discover what processes take place at the core of proton-antiproton collisions. Credit: Fermilab

Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced today (October 23, 2006) the discovery of two rare types of particles, exotic relatives of the much more common proton and neutron.
