Understanding collectivity collectively: CERN-wide activities in the LPCC group

We will discuss the activities in the context of the LPCC groups. These LHC-wide groups coordinate experimental comparisons for various topics:
https://lpcc.web.cern.ch/LPCC/

The group on minimum bias and underlying event has decided to include also collectivity in small systems as one of their topics.

While this part of the workshop is targeted at the LHC experiments, other participants of the workshop may of course be present.
