## Summary
108+
109+
This comparison shows the kinematic distributions between Campaign 2025-07 and Campaign 2025-08 for the Sullivan process e + p → e' + K⁺ + Λ at 10×100 GeV.
110+
111+
Key areas to examine for changes:
112+
- **Beam characteristics**: Check for any modifications in beam spread or crossing angle
113+
- **Scattered electron**: Compare DIS kinematic coverage
114+
- **Kaon production**: Look for differences in momentum and angular distributions
115+
- **Lambda spectator**: Verify consistency in spectator baryon kinematics

125+
126+
This analysis shows the kinematic distributions for the Sullivan process e + p → e' + K⁺ + Λ at {{ energy.replace('x', '×') }} GeV:
127+
128+
- **Incident particles**: Show narrow momentum distributions centered around beam energies
129+
- **Scattered electron**: Exhibits broad kinematic range typical of DIS
130+
- **Kaon**: Produced meson with significant transverse momentum
131+
- **Lambda**: Spectator baryon carrying most of the initial proton momentum
132+
133+
The distributions confirm the expected kinematics for meson structure studies at the EIC.
