摘要：

We proceed to the first phenomenological study of prompt eta(c)' hadroproduction at next-to-leading order in alpha(s). Based on heavy-quark-spin symmetry, which is systematically used in quarkonium-production phenomenology, we demonstrate that prompt eta(c)' can be studied at the LHC with the existing data. We emphasise its relevance to constrain psi' production, in the same way as the first prompt eta(c) data at the LHC lately strongly impacted the phenomenology of J/psi studies. (C) 2018 The Authors.
