The analysis uses the \$\mathrmMS\$ scheme for \$\alpha\_s\$ and all quark masses and is performed in the fixed-flavor number scheme for \$n\_f=3, 4, 5\$. Essential new elements of the fit are the combined data from HERA for inclusive deep-inelastic scattering (DIS), data from the fixed-target experiments NOMAD and CHORUS for neutrino-induced DIS, and data from Tevatron and the LHC for the Drell-Yan process and the hadro-production of single-top and top-quark pairs. The theory predictions include new improved approximations at NNLO for the production of heavy quarks in DIS and for the hadro-production of single-top quarks. The description of higher twist effects relevant beyond the leading twist collinear factorization approximation is refined. At NNLO we obtain the value \$\alpha\_s^(n\_f=5)(M\_Z) = 0.1147 0.0008\$.
