Description
Improved determination of the strange sea distribution in the nucleon is presented. Recent charm production data in neutrino-nucleon deep-inelastic scattering by the NOMAD and CHORUS experiments and from charged current inclusive deep-inelastic scattering at HERA are used. The results are consistent with the data from the ATLAS and the CMS experiments on the associated production of $W^{\pm}$-bosons with c-quarks. The joined QCD analysis of the LHC measurements of W+charm production and of data of CHORUS experiment is performed.
