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 a vertex detector) at IHEP accelerator U-70. Modernization of SVD setup: upgrade of the vertex detector electronics, construction of a liquid hydrogen target, trigger of events with high multiplicity, and an electromagnetic calorimeter. Measurements of the partial cross section of pN interactions up to the charged particles multiplicity of about 30. Measurements of multiplicity and spectrum of photons. Study of multiparticle correlations. Check of the thermalization hypothesis for the multiparticle system and other models of multiparticle production. Development of the Monte Carlo simulation for events with high multiplicity.

Expected main results in 2003:
