Description

We will report on recently published experimental results on the proton longitudinal spin structure at long distance. The inclusive data were taken with the Jefferson Lab CLAS spectrometer in Hall B by experiment EG4. They covered the very low $Q^2$ domain, down to $Q^2 = 0.012$ GeV$^2$, where Chiral Effective Field Theory ($\chi$EFT) is applicable, thereby providing a test of its predictions.
