Semi-Inclusive Deep-Inelastic Scattering (SIDIS) is one of the processes that allow us to extract information about Transverse Momentum Distributions (TMDs) and will be the main channel to access TMDs at the future Electron Ion Collider (EIC).
We provide an estimate of the impact that EIC data will have on unpolarized Transverse-Momentum Dependent (TMD) Parton Distribution Functions (PDFs) and Fragmentation Functions (FFs). We performed a study that shows that including EIC pseudo data in a global fit allows us to better determine the non-perturbative parameters of unpolarized TMD PDFs and FFs, which are much more constrained than in the global fit performed by the Pavia group in 2017.
