Resummation effects in the forward production ofZ0+jetat the LHC

Abstract: We calculate several differential cross sections for Z0 and high-pT jet production in the forward rapidity region at the LHC using the hybrid High Energy Factorization. We test various unintegrated gluon distributions involving subleading BFKL effects (such as kinematic constraint, running strong coupling and DGLAP correction) and compare the results with experimental data obtained by the LHCb experiment. We find that the hard scale dependence of unintegrated gluon distributions, which effectively resums the S… Show more

“…The complete set of evolution equations in the linear regime can be also derived through the projector method [46], see [47] for a recent approach. There have been many calculations attacking various processes where the usage of unintegrated parton distributions is important, see for example [48][49][50][51][52][53][54][55][56][57][58][59] where mostly forward jet observables in hadroproduction were addressed. These calculations, however, use universal unintegrated gluon distributions, the same for any color flow.…”
