$η_c'$ Hadroproduction at Next-to-Leading Order and its Relevance to $ψ'$ Production

Paper

Abstract

We proceed to the first study of

prompt hadroproduction at next-to-leading order in

. Based on heavy-quark-spin symmetry, which is systematically used in quarkonium-production phenomenology, we demonstrate that prompt

can be studied at the LHC with the existing data. We emphasize its relevance to constrain

production, in the same way as the first prompt

data at the LHC lately strongly impacted the phenomenology of

studies.
