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

Introduction


Project is initiated & led by A.Sissakian & A.Sorin

4

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

Introduction

The MPD will be operated in heavy ion collisions over atomic mass range A=1-197at the energy up to √SNN = 11 GeV/u (for Au+79) The design average luminosity: L= 1027 cm2/s


5

Yield & spectra of particles (charged, neutrals, strange)

Study of the K/π (strangeness to entropy) ratio

Anisotropic collective flow

Femtoscopy (momentum correlations)

e-m probes

P (CP) - asymmetryOther 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

Timetable of the MPD works

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.)

Conclusions

22


• Physics motivation & competitiveness are well proven

by the White Book & Round Table -4

• The MPD design & R&D are progressing well- the first version of the CDR is available

• The Working Groups are working towardsthe 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

Thank you
