The data sample used corresponds to an integrated luminosity of 6 fb(-1) collected at a center-of-mass energy of 13 TeV with the LHCb detector. In events with a Z boson and a jet, the fraction of charm jets is determined in intervals of Z-boson rapidity in the range 2.0 < y(Z) < 4.5. A sizable enhancement is observed in the forwardmost y(Z) interval, which could be indicative of a valencelike intrinsic-charm component in the proton wave function.", optnote="WOS:000767187300001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5170), last updated on Mon, 28 Mar 2022 07:21:45 +0000", issn="0031-9007", doi="10.1103/PhysRevLett.128.082001", opturl="https://arxiv.org/abs/2109.08084", opturl="https://doi.org/10.1103/PhysRevLett.128.082001", language="English" }
