Description
The exploration of medium modification of unpolarized structure functions in nuclei has been underway for several decades. The theoretical descriptions of this effect, known as the “EMC effect”, are numerous and there is currently no universal community consensus about its cause, although connections to short-range correlations do appear to be plausible. In this talk I will discuss something new, the very first investigation into the modification of polarized structure functions in the nuclear medium. I will discuss an approved Jefferson Lab experiment to measure bound proton spin structure functions in the 7Li nucleus with an 11 GeV electron beam, and also the possibilities to extend this measurement to an upgraded Jefferson Lab with a 22 GeV electron beam.
