Good agreement between measurements and NLO QCD predictions.
Wide range of Q2 values analyzed for {}S extraction.
Abstract
The data from the HERA experiments H1 and ZEUS allows a precise extraction of the strong coupling constant {\alpha}S with the highest experimental precision (sub 1%). A review of recent measurements of jet cross sections in neutral current deep inelastic scattering (NC DIS) at HERA is presented and compared with theoretical NLO QCD predictions. The latest determinations of {\alpha}S in a large range of Q2 are shown.
