Exclusive electroproduction of ρ0 and J/ψ mesons at HERA

Creators

Description

Exclusive production of and mesons in ep collisions has been studied with the ZEUS detector in the kinematic range GeV, GeV for the data and GeV, GeV for the data. Cross sections for exclusive and production have been measured as a function of W and t. The spin-density matrix elements , and Re have been determined for exclusive production as well as and for exclusive production. The results are discussed in the context of theoretical models invoking soft and hard phenomena
