2nd LHC HI WG meeting

Tuesday 8 Feb 2022, 16:00 → 18:10 Europe/Zurich

Second LHC HI WG meeting dedicated to event multiplicity estimators.

The experiments have presented results and shared thoughts on multiplicity measurements and centrality estimation.

Discussions occurred on the different potential biases regarding the latter. No consensus has been reached, and the conveners concluded that more meetings on these topics should be organized.
