at the JINR Nuclotron-M Facility
| Leader: | A.D. Kovalenko |
| Deputies: | N.M. Piskunov V.P. Ladygin M. Finger (Jr.) R.A. Shindin |
Participating Countries and International Organizations:
Belarus, Bulgaria, CERN, Czech Republic, France, Germany, Japan, Poland, Romania, Russia, Slovakia, Sweden, Switzerland, Ukraine, United Kingdom, USA, Uzbekistan.
Scientific Programme:
Methodical support of the experiments at polarized beams of the Nuclotron-M and NICA facilities, including development of polarimetery systems. Measurement of analyzing power for the reaction p + CH2 at polarized proton momentum up to 7.5 GeV/c and polarized neutrons momentum 4.5 GeV/c at the setup ALPOM-2. Measurement of tensor analyzing power and spin correlation in d
p reaction in the deuteron core area
with the use of polarized 3He target and polarized deuteron beam of the Nuclotron-M.
Study of 2N- and 3N-correlations in deuteron-proton elastic scattering and deuteron break-up reactions
at the Nuclotron internal target. Works on modernization of Saclay-Argonne-JINR polarized proton target (setup PPT).
The analysis of set of the np spin observables at 0 o (the total np cross
section differences), using polarized targets and quasi-monochromatic relativistic 1.2-3.6 GeV
neutron beams. Determination of the forward scattering NN amplitudes over this energy region. Comparison of the
obtained data with QCD motivated model calculations. Study of charge-exchange processes in dp--interactions at
the setup STRELA. Development of theoretical models for description of the simplest nuclear systems taking into account
relativistic effects, meson and quark-gluon components of the internal movement. Theoretical analysis of experimental
data obtained at Nuclotron-M.
The study of the properties of strongly interacting matter utilizing polarization phenomena in hadron-nucleon and
lepton-nucleon interactions, and in the decay of polarized radioactive atomic nuclei. Study of highly excited nuclear
matter and collective effects in nuclear media; delta and other nucleonic resonance excitations on protons and nuclei.
Preparation of the setup DELTA-LNS and data taking on the light neutral mesons production in polarized nucleons and
nucleus interactions.
Expected main results in 2017:
- Works:
a) study of low energy proton and deuteron polarimeter within the frames of the program: "Spin Physics Research Infrastructure at the Nuclotron";
b) preparation to the measurements of analyzing power of neutron-CH scattering at polarized neutron momentum from 3 to 4.5 GeV/c.
- Completion of stages of the approved projects and collaborative protocols within the frames
of their real financial support, including:
a) realization of the projects ALPOM-2 and DSS;
b) experiments at the setup ALPOM-2 analysis of the collected data from DELTA-SIGMA setup.
- Participation in the design and construction of BM@N setup in accordance with general plan.
- Participation in the joint scientific programs and experiments, design and test of
the new detectors and electronics for the use at SPS LHC, FCC (CERN), RHIC (BNL), TJNAF (Newport News),
FAIR (GSI) in accordance with the approved collaborative agreements.
- Continuation of the development of the new methods to calculation of the amplitudes and polarization
characteristics of deuteron fragmentation and deuteron elastic scattering on protons and nuclei taking
into account FSI and relativistic effects.
