摘要：Hard exclusive production in deep inelastic lepton scattering provides new access to the poorly
known Generalized Parton Distributions (GPDs) of the nucleon. Different observables for hard
exclusive production of photons and mesons have been measured by the HERMES experiment.
Emphasis is given to recent results which help determine the total angular momentum of quarks
in the proton.
