Strange sea determination from collider data

We consider determinations of the strange sea in the nucleon based on QCD analyses of data collected at the LHC with focus on the recent high-statistics ATLAS measurement of the W±- and Z-boson production. We study the effect of different functional forms for parameterization of the parton distribut...
