International collaboration and free exchange of knowledge have been for many decades key assets in the progress of particle physics. In particular, international workshops have provided open forums for the sharing of new scientific results and fostering discussion. However, in the current political context the role and format of global scientific cooperation have become challenging.
The online-only format of this workshop, marking the first in what we hope to be a series, reflects our commitment to universal open attendance and removes discriminating constraints such as those arising from politics, travel, cost for participation, and minimize environmental impacts.
The workshop will run for only 2h per day, to minimize the inconvenience across time zones, and to allow enough time for personal work as well as meetings and chats among participants.
