Summary
This analysis shows the kinematic distributions for the Sullivan process e + p → e' + K⁺ + Λ at 10×100 GeV:
- Incident particles: Show narrow momentum distributions centered around beam energies
- Scattered electron: Exhibits broad kinematic range typical of DIS
- Kaon: Produced meson with significant transverse momentum
- Lambda: Spectator baryon carrying most of the initial proton momentum (~95-100 GeV)
The distributions confirm the expected kinematics for meson structure studies at the EIC.
