PDF constraints from CMS measurement of W charge asymmetry and inclusive jet cross sections at 8 TeV — •Engin Eren and Katerina Lipka — Notkestraße 85, 22607 Hamburg

In this talk, the impact of the CMS measurements on the knowledge of the proton structure is discussed. The measurements of the W-boson charge asymmetry and of inclusive jet cross sections at a center-of-mass energy of 8 TeV are used in a QCD analysis to determine the parton distribution functions. For this purpose, the open-source framework HERAFitter is used. A significant reduction of the uncertainties on the gluon and valence-quark distributions is observed.
