HEP Journal-club @ LBNL

Welcome to LBNL ATLAS Journal club for Graduate students (and other students working with the ATLAS group).

We meet weekly on Mondays at 15:00-16:00 at Berkeley Lab.
Check the table below for the room, but usually in 50B-4205 which is in the Building 50 complex near blackberry gate (bus stop 65). Subscribe to mailing list at ATLAS-journal-club@lbl.gov for future updates.

Each week one of our members will chair the discussion, which effectively mean they’ll have a specific set of points they wish to go over.
However, everyone is expected to have read the paper and contribute to the discussion! No slides allowed, but supplementary material/plots is fine!
