Description
A first determination of the strong coupling $\alpha_s$ in
next-to-next-to leading order (NNLO) from inclusive jet and dijet
production in deep-inelastic scattering at HERA is presented.
The strong coupling is determined in a fit of jet data collected by the H1
experiment in the range of momentum transfer $5.5 < Q^2< 15000$ GeV${}^2$
and jet transverse momenta $p_T>5$ GeV. The running of the strong
coupling is probed in a single experiment over one order of
magnitude in the remornalisation scale $\mu_r$. NNLO predictions were
obtained using the program NNLOJET, where the corresponding
calculations are based on antenna subtraction techniques.
