“…A preliminary measurement has been performed by the collaboration at 7 TeV [204] and work is ongoing to finalize the result with the Run-I dataset. Measurements of the associated production of Z bosons with b-quarks and D mesons have been performed in [205,206] while more recent measurements of W production in association with beauty and charm jets are also presented in [207]. In the latter measurement, the jets are identified using the algorithm outlined in [208] achieving a 65% (25%) efficiency for identifying beauty (charm) jets with a corresponding light-jet mis-tag rate of 0.3%.…”

The accurate determination of the parton distribution functions (PDFs) of the proton is an essential ingredient of the Large Hadron Collider (LHC) program. PDF uncertainties impact a wide range of processes, from Higgs boson characterization and precision Standard Model measurements to new physics searches. A major recent development in modern PDF analyses has been to exploit the wealth of new information contained in precision measurements from the LHC Run I, as well as progress in tools and methods to include these data in PDF fits. In this report we summarize the information that PDFsensitive measurements at the LHC have provided so far, and review the prospects for further constraining PDFs with data from the recently started Run II. This document aims to provide useful input to the LHC collaborations to prioritize their PDF-sensitive measurements at Run II, as well as a comprehensive reference for the PDF-fitting collaborations.

“…As in Refs. [41][42][43], jets are required to satisfy p T (j) > 20 GeV and 2.2 < η(j) < 4.2 to ensure nearly uniform jet reconstruction and c-jet-identification efficiencies, and only the highest-p T jet in each event is considered (all other jets are ignored). Ref.…”

Measurement of Z bosons produced in association with charm jets ðZcÞ in proton-proton collisions in the forward region provides a direct probe of a potential nonperturbative (intrinsic) charm component in the proton wave function. We provide a detailed study of the potential to measure Zc production at the LHCb experiment in Runs 2 and 3 of the LHC. The sensitivity to valence-like (sea-like) intrinsic charm is predicted to be hxi IC ≳ 0.3%ð1%Þ. The impact of intrinsic charm on Higgs production at the LHC, including Hc, is also discussed in detail.
