Title: The QCD Running Coupling

Abstract:


We will discuss the QCD running coupling, αs, starting from its definition and meaning in the QCD's perturbative domain. We will then show how the definition of αs can be extended into the non-perturbative domain. Such extension is not unique and we will focus on the extension based on the concept of effective charges. This particular extension is especially useful as it permits us to measure αs in the non-perturbative domain. We will describe the measurement and its result.
Furthermore, such effective charge can be computed using the AdS/CFT correspondence. We will briefly describe the calculation and then compare its result to the measurements and to other non-perturbative determinations of αs.



Sincerely,
