    The aim of this meeting is to examine how positivity constraints could be employed by LHC experiments and how to facilitate this use, e.g. by expressing them in an agreed-upon operator basis, by centralising them into a shared piece of code and/or online updatable repository.

    Ideas relative to these questions can be posted in this gDoc ahead of the meeting and to seed the open discussion.

    This meeting will be held on Zoom, with participants present at CERN being offered the possibility to gather in a physical room.
