Abstract
The cross section of the exclusive η electroproduction reaction e p → e ′ p ′ η was measured at Jefferson Laboratory with a 5.75 GeV electron beam and the CLAS detector. Differential cross sections d 4 σ / d t d Q 2 d x B d ϕ η and structure functions σ U = σ T + ε σ L , σ T T , and σ L T , as functions of t , were obtained over a wide range of Q 2 and x B . The η structure functions are compared with those previously measured for π 0 at the same kinematics. At low t , both π 0 and η are described reasonably well by generalized parton distributions (GPDs) in which chiral-odd transversity GPDs are dominant. The π 0 and η data, when taken together, can facilitate the flavor decomposition of the transversity GPDs.
