P5 (Particle Physics Project Prioritization Panel) makes recommendations on the next 10 years of the US particle physics program within the 20 year context to HEPAP, which advises DOE and NSF. It builds on the extensive community involvement in the Snowmass study. This meeting is part of a series of town halls for information gathering for the panel to learn the aspiration of the community and basic ideas on costs and schedule of proposed projects. 

Town Halls have a set of invited talks on overview of scientific opportunities as well as concrete projects, including their costs and schedules. They also have sessions for the community members to make short (~5min) remarks about their vision for the field, exciting science, projects, and issues of the community. People are encouraged to propose remarks, especially early career scientists. There will be also a time for "open-mic" session for discussions.  

This meeting will take place at both Fermilab and Argonne and will cover: Neutrino, Rare Processes and Precision Frontier,  and High-Energy Astrophysics. 

  • 21st March morning - NAS EPP town hall at Fermilab ( This event does not use the same zoom
  • 21st March afternoon  - P5 town hall on-site at Fermilab 
  • 22nd March  - P5 town hall on-site at Fermilab 
  • 23rd March - P5 town hall on-site at Argonne
  • 24th March - CLOSED SESSION at Fermilab (P5 Committee Only)

Fermilab and Argonne are located in the Chicago-land area, separated by a ~30min drive depending on traffic. See map below. 

The Town Hall will be a hybrid event. Both in-person and remote participants must register.  Foreign nationals will receive instructions via email to submit additional information for site access. Separate site access approvals are needed for Fermilab and Argonne, and if needed you will be contacted separately by both labs. 

Once site access is approved, you will be sent a QR code (for Fermilab) and gatepass instructions for Argonne, which will allow you access to the lab(s). You will receive separate permission for Fermilab and Argonne. They are not interchangeable. Access to both Fermilab and Argonne will only be permitted when all procedures for each have been successfully completed.  See Site Access page for more details. 

Registration for in-person participation has closed,  to allow access requests to be processed, but remote participants can register at any time. Zoom information will be provided for all registered participants in your confirmation email.
