The seminars used to start at 10 am in SR3 at DESY in Zeuthen. There would normally be a common breakfast and paper discussion till around 10:30, when the presentation starts.

Due to the Covid-19 crisis the AP seminars will be Zoom meetings for the time being  

  • Journal club paper discussions start at 10:30
  • The seminar talk starts at 10:45
  • The talk length is reduced to 30 minutes, not counting the discussion time
  • Join the seminar zoom meeting:
  • The meeting is password protected. The password is shared in the email announcement. If you didn't receive it, contact the organizers.

Paper discussions

Paper discussions will alternate between a paper selected by someone from the gamma, neutrino, and THAT groups. The paper chasers are in charge of organizing this and finding volunteers. They are: Sylvia Zhu (gamma, sylvia.zhu [at], Wing Yan Ma ( [at] desy.deneutrino) and Paul Morris (THAT, paul.morris [at] Ideally, the papers should be posted a few days ahead of time so that people have a chance to read them. Note that duos of presenters, rather than single presenters are possible. The upcoming schedule of papers to discuss is below:
