P5 News

• 8/1-4: On Aug1, Dr. Asmeret Berhe, the Director of the Office of Science, joined the P5 meeting and presented her view on workforce and DEI issues. In addition, Dr. Harriet Kung, the Deputy Director for Science Programs in the Office of Science, came to join the panel in person and discusses far-reaching issues about the role of HEP in the Office of Science. She also keenly listened to our concerns about the site access issues at the national labs. On the following days, the panel had intense discussions throughout the week to formulate the recommendations. The whole panel worked very constructively and collegially. We also listened to the conveners of the Snowmass computing frontier.
• 7/11-14/2023: The third closed session in Santa Monica, CA. Sally Seidel is the interim HEPAP chair and attended the P5 meeting for the first time. We heard reports from Committees of Visitors, both from DOE and NSF, and from Jlab and Oak Ridge about their visions.
• Many meetings of the working groups.
• 6/21-23/2023: The second closed session in Gaithersburg, MD. The first day was intended to be at NSF in Alexandria, but the visit by the Indian Prime Minister Modi booted us out. Yet we had a very fruitful discussion with NSF. Jay’s committee presented their preliminary findings. We also heard from Cole Donovan who worked at State Department on international agreements, and DOE/HEP program managers.
• Many meetings of the working groups.
• 5/31-6/2/2023: The first closed session in Austin TX. We formed many working groups for detailed discussions.
• 6/27/2023: The second and last virtual town hall hosted by Virgina Tech. It focused on theory, small projects, and research and development across frontiers including but not limited to instrumentation and computing. Very useful. This meeting marks the end of the information gathering phase of the panel.
• 6/5/2023: The first virtual town hall hosted by UT Austin. We felt strongly that not all town halls are hosted by national laboratories but also by universities. It focused on university research, the landscape of HEP across the nation, and the early career community. In particular, we had an exclusive session with early career scientists only, ad we learned about issues that had not been talked about openly.
• 5/3-5/2023: The fourth Town Hall at SLAC. It focused on Underground, Accelerator, Theory Frontiers, as well as Community Engagement. In addition to science, we learned about Public Policy and Government Engagement from Louise Suter (Fermilab), Early Career report from Julia Gonski, communiating HEP to the public by Sean Carroll, climate of the field from Erin Hanson, and the situation with non-physicists in our community from Cindy Joe. All of them are important issues. It also marked the last meeting attended by JoAnne Hewett as an ex officio member.
• 4/28/2023: P5 had an internal tutorial on various collider options and their challenges. Very useful.
• 4/20/2023: A P5 closed meeting with NSF on the infrastructure issues at the South Pole with Debra Fisher (Director AST), Jim Ulvestad (Director OPP), and Nigel Sharp (AST). The issue is not trivial, and clearly requires a congressional action to coordinate NSF with the military.
• 4/15/2023: A session at the APS/DPF meeting in Minneapolis. Good interaction with the community.
• 4/12-24/2023: The third Town Hall at Brookhaven. It focused on Energy, Instrumentation, Computational Frontiers, as well as Gravitational Wave. Fabiola Gianotti (CERN) came in person, while we heard from Asian programs from Masa Yamauchi (KEK) and Yifang Wang (IHEP) on zoom. It was announced that JoAnne Hewett will be the next director of Brookhaven the day before the meeting. She will be stepping down from the HEPAP chair.
• 4/11/2023: The cost subcommittee was formed and started the work.
• 3/21-24/2023: The second Town Hall at Fermilab and Argonne. It focused on Neutrino, Rare Processes and Precision Frontier, High-Energy Astrophysics. We tried to overlap with EPP2024 at Fermilab. Very good communication between two panels.
• 2/22-23/2023: The first Town Hall at LBNL focused on the cosmic frontier with 513 registrants. Lunch is provided outside in an unusually cold weather in Berkeley. Wonderful talks on science, in addition to a talk by Fiona Harrison on the Astro 2020 report, and by Andreas Haungs on the European Astroparticle Physics Strategy. The open remark session was oversubscribed by a factor of three, followed by a nice reception overlooking the Bay Area. It was the first time for the panel members to meet in person.
• Strong demand from the community to provide American Sign Language and Live Captioning at Town Halls. DOE approved expenses. Lots of challenges with logistics and support. We also decided not to record the talks (except for the internal use by the panel) to encourage open discussions.
• 2/6/2023: The kick-off meeting of the panel with DOE and NSF on zoom. The first briefing on the budget process, and the discussion on the work plan.
• 1/23/2023: Yuri Gershtein from Rutgers agreed to be on the panel. He would provide perspective from US-CMS replacing Meenakshi, with his own expertise.1/30/2023: We could add another member to the panel, Amalia Ballarino from CERN. She will add a crucial expertise on the development of high-field superconducting magnets, as well as perspective from CERN. The panel is now complete.
• 1/1/2023: Very sad news that Meenakshi Narain has passed away. She played a major role in the Snowmass process on the energy frontier. She was on the list of panel members. A big shoe to fill to replace her.
• By the end of 2022, we managed to assemble the panel, in consulation with DOE and NSF. A very diverse panel with amazing expertise spanning all areas of our field.
• JoAnne and Hitoshi attended the EPP2024 virtual meeting. The charge to P5 was shown for the first time.
• JoAnne and Hitoshi attended the EPP2024 meeting in Irvine.
• Intense discussions to form the panel by JoAnne, Karsten, and Hitoshi. Paying careful attention to balance among scientific expertise, geography, DOE vs NSF, age, including international memberships.
• 11/3/2022: Karsten Heeger from Yale agreed to be the deputy chair of P5. Way to go!
• 11/2/2022: Charge was issued to HEPAP from DOE and NSF. Now we can get our work started!
• Constant discussion with JoAnne Hewett on the membership of the panel. Yet we had to wait till the new director of HEP is confirmed, and the charge is issued officially.
• 9/7/2022: Murayama had the first meeting with NSF. Met officers of NSF PHY, Denise Caldwell, Jean Allen, James Shank, Darren Grant, William Wester, Kaushik De. Also meeting the directorate of MPS, Sean Jones, Saul Gonzalez.
• 9/7/2022: Murayama had the first meeting with DOE. Met Harriet Kung, Michael Procario, Glen Crawford.

Town Halls

We will have four town hall meetings in hybrid mode with people in the community to give short presentations on issues, visions, science, projects of interest to the field, including an open-mic session. If people want to speak privately with the panel, we will try to accommodate the request as much as we can, especially for early career scientists. They are not tied to any specific Snowmass frontiers.

In addition, we will have a set of invited talks at the meetings cenetered around some of the Snowmass frontiers, on the visions of the communities and specific set of projects. This is an important part of the information gathering mode for the panel.

Hybrid Town Halls

• P5 Town Hall at Lawrence Berkeley National Laboratory, February 22-24, 2023 with a focus on Cosmic Frontier (except for High-Energy Astrophysics)
• P5 Town Hall at Fermilab/Argonne, March 21-24, 2023 with a focus on Neutrino, Rare Processes and Precision Frontier, High-Energy Astrophysics
• P5 Town Hall at Brookhaven, April 11-14, 2023 with a focus on Energy, Instrumentation, Computational Frontiers
• P5 Town Hall at SLAC, May 2-5, 2023 with a focus on Underground, Accelerator, Theory Frontiers, Community Engagemen

We also held a session “Discussion with P5” at the APS April Meeting on Saturday, April 15, 2023 .

Virtual Town Halls

• UT Austin, university research, the landscape of HEP across the nation, and the early career community, including an exclusive session for early career scientists, June 5, 2023
• Virgina Tech, theory, small projects, and research and development across frontiers including but not limited to instrumentation and computing, June 27, 2023

Closed Meetings

Over the coming months there will be a series of closed meetings for the P5 panel.

Project Information

In addition to the town halls, the P5 panel will request information on cost, schedule, risks and science goals from projects. P5 chair Murayama has charged a separate sub-panel chaired by Jay Marx to evaluate cost, schedule, and risks. The request for information will be sent out during the week of April 10, 2023 starting with the largest projects in the field.
