The GPD program at COMPASS
In this paper we summarize recent measurements of exclusive reactions at COMPASS, which are a part of the GPD program. New results on the transverse target spin asymmetries for exclusive 0 production are presented. Some of these asymmetries are sensitive to the GPDs E , which are related to the orbi...

Sumario: | In this paper we summarize recent measurements of exclusive reactions at COMPASS, which are a part of the GPD program. New results on the transverse target spin asymmetries for exclusive 0 production are presented. Some of these asymmetries are sensitive to the GPDs E , which are related to the orbital angular momentum of quarks. Other asymmetries are sensitive to the chiral-odd, transverse GPDs H T . Planned measurements of Deeply Virtual Compton Scattering, which are a part of the approved COMPASS-II proposal, are also discussed. The main aim of these measurements is access to the GPDs H , which are related to the 3-dimensional nucleon tomography. |
