Priority:

Status:

Extended

Search for Effects of Polarized Hidden Strangeness in Nucleons
(Project NIS)

Leader:

E.A. Strokovsky
A.G. Litvinenko

Scientific Programme:
Obtaining new experimental data on total and differential cross section of

and

production in pp and np interactions at thresholds.
Experimental and theoretical studies of vector meson production mechanisms at threshold in nucleon-nucleon interactions at intermadiate energies.
Data on OZI-rule violation, its energy dependence and dependence on isospin of the NN system in the initial state at nucleon energies close to the

and

production thresholds.
Search and study for production of exotic baryons ("pentaquarks") in pp and np interactions.
A new large acceptance magnetic spectrometer for experiments at intermediate energies with multitracking capability and a particle identification system (PID) based on time-of-flight measurements will be constructed at the Nuclotron extracted beam.

Expected main results in 2007:

Competion of mounting of the tracking system and the detectors for particle identification system.
Production of the 1st MDC; comissioning of TOF, trigger and DAQ systems.
Completion of mass production (in a part) of registering electronics and modules of high voltage supply system.
Study of the setup characteristics at the extracted proton beam. Spectrometer calibrating in binary reactions.
Start of physical data taking at the extracted proton beam.
