Description

Recent developments in the theory of polarized scattering in the small-$x$ regime have led to the construction of novel evolution equations for helicity at small $x$. In recent years, these small-$x$ helicity evolution equations have been used in global analyses of inclusive DIS and now SIDIS cross sections, providing a formalism capable of predicting the unmeasured spin hiding below the lowest accessible $x$. In this talk, I will summarize the theory of spin at small $x$ and the status of its application to global analyses, with an eye toward the future electron-ion collider.
