Priority:

Status:

Approved for completion
in 2008

Study of the Hadron Structure in the Experiments with the COMPASS (NA58), HERMES and H1 (DESY) Spectrometers

Leader:	A.P. Nagajtsev
Scientific leader:	I.A. Savin

Expected main results in 2008:

Participation in the COMPASS data taking run.
Support of HCAL1 during 2008 run.
Performance studies of the tracking detectors MWPC, STRAW, W4/5 for COMPASS.
Performance studies of RICH WALL for COMPASS.
Preparation of the project on the study of Generalized Parton Distributions in COMPASS.
Development of the COMPASS and HERMES software and simulations.
Participation in analysis of COMPASS data recorded in 2002 and 2008.
Theoretical studies of spin effects in COMPASS.
Implementation of the COMPASS software at JINR.
Diffractive structure function F ^D₂ will be measured in DIS processes with a leading proton in the final state.
Measurement of the diffractive inclusive cross section of photo-production and get photo-production hadrons with high transverse momentum.
