Electron-Ion Collision Environment: Distribution of Quark Spin and Orbital Angular Momentum
Sujit Jana, Ashutosh Dwibedi, Vikash Kumar Ojha +1
The future Electron-Ion Collider (EIC) will enable measurements of the same partonic distributions inside both the proton and the nucleus through electron-proton (eP) and electron-…
