Description
We will discuss how data from JLab@22GeV, combined with expected low-$x$ measurements from the EIC, can determine the QCD coupling $\alpha_s$ with an accuracy comparable to that of all current world data combined. Furthermore, this approach represents the first extraction of $\alpha_s$ directly sensitive to effects beyond its leading-order evolution, offering a novel test of perturbative QCD at a fundamental level. Additionally, it opens a possible new window for probing physics beyond the Standard Model, as non-QCD contributions affect the evolution $\alpha_s$ at the next-to-leading order, rather than leading-order level where $\alpha_s$ has been tested to date.
