摘要：

In view of the good agreement between the LHCb prompt-eta(c) data at root s = 7 and 8 TeV and the NLO colour-singlet model predictions -i.e. the leading nu(2) NRQCD contribution-, we provide predictions in the LHCb acceptance for the forthcoming 13 TeV analysis bearing on data taken during the LHC Run2. We also provide predictions for root s = 115 GeV for proton-hydrogen collisions in the fixed-target mode which could be studied during the LHC Run3. Our predictions are complemented by a full theoretical uncertainty analysis. In addition to cross section predictions, we elaborate on the uncertainties on the p (p) over bar branching ratio -necessary for data-theory comparison- and discuss other usable branching fractions for future studies.
