JINR's Participation at the BES-III Physics Research Program |
Leader: | A.S. Zhemchugov |
| Deputy: | A.V. Guskov |
Participating countries and international organizations:
CERN, China, Germany, Poland, Russia, Sweden.
Issues addressed and main goals of research:
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.
The goal of ARIeL project is to develop the research program for a future e +e - collider. The precision of measurements is expected rto be improved
by a 1-2 orders of magnitude with respect to the one at LHC. To reach a precision like this the necessary tools, both theoretical and experimental,
should prepared in advance.
Expected major results in the current year:
- 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.
- Development of the multipurpose MC event generator to describe main processes of e +e - annihilation including
radiative corrections at the level of more than one loop. The generator will take into account the particle polarization
both for initial and final states.
- Development of the standart program codes to calculate the radiation corrections at the level of 2 (for EW interactions)
and 3 (for strong interactions) loops.
- Study of research potential of experiments at CLIC collider in the domain of precision measurements and search of new
physics in the base of full detector simulation.
