CESR set to bow out of B-particle business

26 February 2001

After some 20 years of making milestone contributions to the physics of B-particles (containing the fifth beauty
or “b” quark), the CLEO collaboration at Cornell’s CESR electron-positron collider is now looking to step down
in energy.

It has identified a broad programme of important physics that can be studied in the tau/charm threshold region with a luminosity of 3 x 1032 per cmper s. Simultaneously, Cornell is studying the feasibility of converting CESR to such a facility.

A workshop will be held at Cornell on 5-7 May to provide an opportunity for the elementary particle physics community to explore the opportunities provided by the CLEO III detector operating in this energy/luminosity region. More information is available at http://www.lns.cornell.edu, or e-mail spoke@mail.lns.cornell.edu.

With high luminosity B-factories now in operation at PEP-II, SLAC, Stanford, and KEKB in Japan, CESR is looking for alternative research topics.
