Description

We explore the potential for extracting the longitudinal proton structure function FL(x, Q2) at the future Electron-Ion Collider (EIC) through a Rosenbluth separation method. The impacts of differing assumptions on systematic uncertainties and beam energy scenarios are investigated. With a sufficiently large number of centre of mass energy configurations, the EIC will measure FL with an unprecedented precision and will access a kinematic range that complements both fixed target and HERA data. In the most optimistic scenarios, the EIC data will be a highly competitive direct probe of the proton gluon density.
