Abstract
The centrality of heavy-ion collisions is directly related to the medium
created therein. A procedure to determine the centrality of collisions with the
LHCb detector is implemented for lead-lead collisions at
$\sqrt{s_{\scriptscriptstyle\text{NN}}}=5\, \mathrm{TeV}$ and lead-neon
fixed-target collisions at $\sqrt{s_{\scriptscriptstyle\text{NN}}}=69\,
\mathrm{GeV}$. The energy deposits in the electromagnetic calorimeter are used
to determine and define the centrality classes. The correspondence between the
number of participants and the centrality for the lead-lead collisions is in
good agreement with the correspondence found in other experiments, and the
centrality measurements for the lead-neon collisions presented here are the
first performed in fixed-target collisions at the LHC.

The current recommendation prototype on the Apollo Repository will be turned off on 03 February 2023. Although the pilot has been fruitful for both parties, the service provider IKVA is focusing on horizon scanning products and so the recommender service can no longer be supported. We recognise the importance of recommender services in supporting research discovery and are evaluating offerings from other service providers.
