Description

With the detector instrumented in the forward region, the collected Z boson events in the LHCb acceptance can be used to probe the proton structure. In this talk, the latest Z boson related measurements will be presented: the Z boson production cross-section measurement at 13 TeV, the Z boson angular coefficients measurement, and the measurement of Z+ c jet events for probing intrinsic charm. The potential contributions of the LHCb data to the global PDF fits will be demonstrated via these analyses, including the sea quark in the larger x region, the transverse momentum dependent (TMD) PDFs, and the intrinsic charm in the proton.
