Status: In-progress

JINR's Participation at the BES-III Physics Research Program

Leader:     A.S. Zhemchugov

Participating Countries and International Organizations:
China, Russia.
Scientific Programme:
The BES-III experiment at the electron-positron collider BEPC (IHEP CAS, Beijing, China) is aimed at systematic and precise measurements in -charm domain. The main goals of the experiment include light hadron spectroscopy, study of charmonium spectrum and transitions, study of open charm particles like D and Ds mesons, -lepton physics and search for new exotic XYZ states. Data taking started in 2009. The world largest sample of J/, (3686), (3770), (4040) is already collected. Scan in the energy range 2.0-4.6 GeV is performed for R-ratio measurement. Unique sample in the energy range 4.2-4.6 GeV is collected to search for new XYZ states.

Expected main results in 2018:
  • BES-III data analysis.

  • Development of offline software and analysis tools

  • Development of the distributed computing system (integration of cloud resource).

  • Development of high-performance PWA software using HybriLIT cluster.
