Priority:

Status:

New

Study of the Nucleon and Barion Structure at CERN
(COMPASS, NA58) and DESY (HERMES, H1)

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

Expected main results in 2009:

Participation in the COMPASS data taking run.
Support of HCAL1 during 2009 run.
Support of MW1 during 2009 run.
Performance studies of the tracking detectors MWPC, STRAW, W4/5 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.
Measurement of the diffractive inclusive cross section of photo-production and get photo-production hadrons with high transverse momentum.
