Description
An extendend QCD analysis of the new combined inclusive HERA was
performed at NLO, also including HERA data on jet and charm production.
This enables the simultaneous measurement of parton distribution
functions and the strong coupling using data from HERA alone. The strong
coupling is measured to be $\alpha_s(M_Z)$= 0.1182 ±0.0008(exp) ±0.0005(model/param.) ±0.0012(hadronisation) ${}^{+0.0037}_{-0.0030}$ (scale).
