This cleaner collision environment allows for a more detailed examination of the structures of these particles at a very small scale.
One of the key mysteries that researchers hope to unravel with the Electron-Ion Collider is the origin of proton mass. While the mass of a proton is well-established, the contribution of quarks to this mass is surprisingly small. The majority of the proton’s mass comes from the strong force interactions within the particle, a phenomenon that is not yet fully understood.
Additionally, the study of proton spin presents another intriguing puzzle. Originally thought to be solely attributed to the quarks within the proton, further research has revealed that the situation is more complex. Understanding the factors that contribute to proton spin is a challenging and essential pursuit in the field of particle physics.
