Precision Measurements of αs at HERA
Description
The precision measurements of the strong coupling constant, αs, and its energy-scale dependence carried out at HERA by the H1 and ZEUS Collaborations are reviewed. An average value of α-bars(MZ) = 0.1186 ± 0.0011 (exp.) ± 0.0050 (th.) is obtained from these measurements. The combined HERA determinations of the energy-scale dependence of αs clearly show the running of αs from jet data alone and are in agreement with the running of the coupling as predicted by QCD
