Recently, 30-GeV proton beam became available at the high momentum beamline of the J-PARC Hadron Experimental Facility. A following project of beamline upgrade will make available negative and positive secondary π/K/p beam up to 20 GeV/c. We will study the nucleon partonic structure utilizing the high-momentum hadron beams. The generalized parton distributions (GPDs) of nucleon can be accessed by various single diffractive hard exclusive processes (SDHEPs): a pure hadronic process (p + p → p + π + B), a diphoton production process (π− + p → γ + γ + n), and an exclusive Drell-Yan process (π− + p → μ+ + μ− + n). Measurements of these reactions give complementary information of nucleon GPDs to one from lepton-induced exclusive reactions.
