- Conclusion
3Introduction
- Project NICA/MPD is dedicated to
- study of hot dense baryonic matter
- and
- development of the home accelerator facility
- providing relativistic heavy ions polarized
beams - all these allow to start a new strategic course
of JINR - towards the leading role in the relevant fields
- of high energy physics
- Project is initiated led by A.Sissakian
A.Sorin
4Introduction
- A conceptual design of MPD is developed for
- a study of hadronic matter in various states
- mixed phase / phase transition
- search for critical end-point (triple point ?)
- other extreme states
- The MPD will be operated in heavy ion collisions
- over atomic mass range A1-197
- at the energy up to vSNN 11 GeV/u (for Au79)
The design average luminosity L 1027 cm2/s
5Physics tasks
- Yield spectra of particles (charged,
neutrals, strange) - Study of the K/p (strangeness to entropy) ratio
- Anisotropic collective flow
- Femtoscopy (momentum correlations)
- e-m probes
- P (CP) - asymmetry
Other studies dense cold matter

Progress of the MPD project preparation
- The first MPD concept was presented in LoI
- issued in February 2008
-
- - it is now modified
- The first version of MPD CDR was issued
- in June 2009
- Now the version 0.6
- is available
- It will be developed further until
- mid of 2010

MPD competitive complimentary to
- running experiments
- STAR, Phenix at RHIC (BNL)
- NA49/NA61 at SPS (CERN)
- HADES at SIS-18 (GSI)
- ALICE at LHC (CERN)
- in preparation
- CBM at SIs100/300 (GSI)
- MPD advantages
- optimal energy range for max baryonic density
- close to 4 pi geometry
- homogeneous acceptance resolution functions
versus measured scanned parameters - (kinematics, b, energy etc.)
22Conclusions
- Physics motivation competitiveness are well
proven - by the White Book Round Table -4
- The MPD design RD are progressing well
- the first version of the CDR is available
- The Working Groups are working towards
- the first prototypes to be ready by the end of
2010 -
- The MPD collaboration is permanently growing
- New members are welcome
- Especially appreciated continuation of
- fruitful cooperation with Italian colleagues
-
