Particle Production in pp Interaction with High Multiplicity at 70 GeV
(Project THERMALIZATION)

Leader:   V.A. Nikitin
P.E. Ermolov.

Scientific Programme:
Study of multiparticle dynamics in pN interaction with high multiplicity of secondary particles on modernized setup SVD (Spectrometer with vertex detector) at IHEP accelerator U-70. Modernization SVD setup: upgrade of the vertex detector and electromagnetic calorimeter electronics, construction of liquid hydrogen target, trigger of events with the high multiplicity. Development of the Monte Carlo simulation of events with the high multiplicity. Measurement of partial cross section of pN interactions up to the charged particles multiplicity of about 30. Measurement of multiplicity and spectrum of photons. Study of multiparticle correlations. Check of a thermalization hypothesis for the multiparticle system and other models of multi particle production. Development of analitic and Monte Karlo models for description of the high multiplicity processes.

Expected main results in 2004:
