High-Energy Exclusive Reactions at J-PARC

The construction for a high-momentum beam line at J-PARC has been funded. This beam line will provide primary proton beam of 30 GeV, as well as secondary beams (pion, kaon, antiproton) up to $\sim$15 GeV/c. We discuss the physics opportunities offered by this high-momentum beam line. In particular, the prospect for measuring exclusive dilepton production with meson beams, and the complimentarity of such measurements to the exclusive reactions programs at JLab and COMPASS will be presented.
