Priority:

Status:

Approved for completion
in 2016

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

Leader:

A.S. Zhemchugov

Participating Countries, Institutes 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 2016:

BES-III data analysis.
Development of offline software and analysis tools
Development of the distributed computing system.
