Description
Centrality-dependent charged-hadron production in p-O collisions at top LHC energies is predicted based on a nonequilibrium-statistical relativistic diffusion model. Colour-glass condensate initial conditions are used in a three-sources momentum-space model for gluon-gluon, quark-gluon and gluon-quark sources. Our results [1] are to be compared with pseudorapidity distributions measured in July 2025 at the LHC for sqrt(s_NN)=9.618 TeV p-O collisions [2]. Once these data are available, the transport parameters and the centrality-dependent gluon saturation scale will be adapted to the data through chi^2 minimizations as in our previous work on p-Pb [3], and the updated model can be used for further predictions regarding asymmetric systems that are relevant for astroparticle physics.
