BES III at Minnesota BEPC II link BES III link

BES III is a general-purpose detector based at the BEPCII e+e- collider in China. BEPCII has a 100x improvement in its luminosity over its predecessor, with a design luminosity of 10^33 cm^2 s^-1. The BESIII detector is designed to take advantage of this improvement in luminosity to do light hadron spectroscopy, study charmonium, investigate electroweak and strong physics at the charm scale, and search for new physics. The BEPCII accelerator can deliver over a billion J/Psi or Psi' in a year, or millions of DDbar or DsDsbar in a year. This will allow the BESIII collaboration to achieve new levels of precision in charm-sector measurements.

Minnesota is part of an initiative to expand U.S. involvement in the BES~III program, with specific focus on transferring tools and expertise from CLEO-c to BES III ( Expression of Interest ). Specifically, we are converting our CLEO-c Monte Carlo simulations computer farm to the BES III experiment. Consisting of 180 virtual processors, the computer farm can generate over 10 million CLEO-c ddbar decays per day. BESIII, with its greater luminosity, will require an even larger amount of Monte Carlo than CLEO-c. The BES III offline software is based on GAUDI and uses GEANT4 to generate Monte Carlo, with MySQL to manage databases.
