The factorization of short-distance partonic cross-sections from universal long-distance kinematic distributions is fundamental to phenomenology at hadron colliders. It has been predicted however that observables sensitive to momenta transverse to the direction of an energetic parton cannot be factorized in the usual way, even at high energies. It should be possible to study this factorization breaking using Z+jet production in high-energy proton-proton collisions by studying azimuthal correlations between a Z boson and associated charged hadrons. A plan to perform this measurement with data collected by LHCb will be discussed, along with related work.

Anonymous Report 1 on 2022-2-11 (Invited Report)


The text is written in a very confusing fashion: it is not clear to the audience that "the LHCb measurements"  refers to the reanalysis of the collected data set? Or there will be dedicated new LHCb measurements in the future?

Could the author include the data projection (of the proposed study) for LHCb?  Please show the LHCb equivalent of Fig.1 or project the proposed LHCb data points on Fig.1 with the estimated uncertainty.
