Priority:1
Status: In-progress

Studies of the Nucleon and Hadron Structure at CERN


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

Participating Countries, Institutes and International organizations:
Armenia, Belarus, Bulgaria, CERN, Czech Republic, France, Germany, Israel, Italy, Japan, Poland, Russia, Switzerland, Ukraine, United Kingdom, USA.

Scientific Programme:
Studies of the Primakoff reactions and diffractive proctsses. Studies of the generalized parton distributions in various exclusive processes and participation in construction of new electromagnatic calorimeter. Studies of the exclusive production of photons, pions and vector mesons in DIS and DVCS. Measurements of nucleon structure in the Drell-Yan processes. Study of inclusive and semi-inclusive processes in Deep Inelastic Scattering (DIS) of muons and hadrons on polarized targets. The mesurements of the new structure functions characterizing the transverse quark distributions in polarized nucleons.
Expected main results in 2015:
