Planning Long-Term Strategies for Particle Physics
Europe and U.S.
• Frequency: 7 years (Europe), ~8 years (U.S.)
• Process: ~2 years in total (~1 year on science by the community + ~1 year priorities)

Snowmass: Historical Context
Snowmass Summer Studies: 3 weeks in Snowmass, Colorado
“~a thousand physicists gathered for three weeks to talk
about the future of particle physics in the U.S. — and the rest of the world”
Snowmass Village Snowmass Village
in the Colorado Rockies near Aspen
• Initiated by Division of Particles and Fields (DPF): The DPF is independent of funding
agencies; free to define our science goals as a global community
• Organization and Support from APS, DPF, DPB, (DAP, DNP), NASA, NSF and DOE (also
through the various national labs)
8/1/19 P. Cushman and Y-K Kim DPF 2019 3
Snowmass: Historical Context
Examples (not exhaustive)
• 1982: Concentrate on the next collider: The concept of the SSC was born.
• 1984, 1986 Snowmass Studies on SSC reference design and physics
• 1988: High Energy Physics in the 1990s
• Broader goal – more people (>500)
• 1990: Research Directions for Decade
• SSC + Complementary opportunities
• Topical summer studies continue every couple years, but the decadal study begins to
take prominence as an overall community planning process.
• 2001: A summer study on the future of particle physics
• 2013: Similar in its scope to 2001, but spread out through the year
8/1/19 P. Cushman and Y-K Kim DPF 2019 4
Snowmass 2013 The planning process included more than a year of workshops. It presented a status of the field and exciting opportunities going forward. It did NOT prioritize. • The final reports were completed in about 6 months • P5 (Particle Physics Project Prioritization Panel) takes the scientific input from Snowmass and formulates a strategic plan to address the science within specified funding constraints • A successful Snowmass process results in community buy-in, even when hard budgetary decisions need to be made 8/1/19 P. Cushman and Y-K Kim DPF 2019 5

Snowmass (2012-2013) à P5 (2013-2014)
Particle Physics is Global!!
The worldwide particle physics community can together address the full breadth
of the field's most urgent scientific questions with
– each major player hosting a unique world-class facility at home
– partnering in high-priority facilities hosted elsewhere
Region strategic planning is in the global context

8/1/19 P. Cushman and Y-K Kim DPF 2019 21P5: Strategic Plan for U.S. Particle Physics in the Global Context
A: Constant for 3 yrs + 2% increase (based on 2013 appropriated)
B. Constant for 3 yrs + 3% increase (based on 2014 Presidential budget)
C. Unconstrained (but prioritized)
P5 is a subpanel of the High Energy Physics Advisory Panel (HEPAP)
and is charged by and provides advice to both DOE and NSF
8/1/19 P. Cushman and Y-K Kim DPF 2019 22• P5 is deemed “successful” in DOE budget process
• Don’t start revising
8/1/19 it too
P. Cushman andsoon!
Y-K Kim DPF 2019 23Snowmass è P5 is good publicity DOE is making a big effort to increase public engagement with High Energy Physics https://www.usparticlephysics.org/ P5 is featured prominently. Details from Snowmass 2013. 8/1/19 P. Cushman and Y-K Kim DPF 2019 24
P5 Implementation Status: FY 2019
§ Approximate Construction § Expected Physics
All projects on budget & schedule
• Projects fully funded in FY19
HEP Science Output
– Muon g-2: 1st beam 2017
– Mu2e : 1st data in ~2020
[>$200M] – LHC detector upgrades (ATLAS, CMS, LHCb):
on track for 2019/20 installation
– LSST: full science operations 2023
– DESI: 1st light on April 1, 2019
– DM-G2(SuperCDMS,LZ,ADMX) 1stdata ~2020
• HL-LHC accelerator and detector upgrades
LBNF/DUNE (and PIP-II) started on schedule
• LBNF/DUNE & PIP-II schedules advanced due
to strong support by Admin & Congress
[Project funding needs are projected to decrease in 2025
o Funding for HL-LHC projects complete in FY 2024/2025
o Funding for Line-Item Construction Projects LBNF/DUNE
and PIP-II peak in FY 2025, and completes by FY 2027/2028
o Only CMB-S4 project remains in the list of P5 recommendations
– Future Collider project has dependency on strategic planning
in Europe and Asia
o Continuous new ideas and new input to budget formulation is
critically important to continue the pursuit of funded Discovery
Science (new Projects)
o Submit new Mission Needs (CD-0) at the rate of one/year from
FY 2019 through FY 2035+

} When the current P5 report was released in May 2014, the FY 2015 budget
was already in Congress and the FY 2016 budget was being formulated
} To provide timely input to the FY 2025 budget formulation, the “next P5”
report will be required by March 2023

28Timeline for updating the U.S. Strategy
o May 2014 P5 report was successful because it was well informed by the
science community, including information from:
– 2010 New Worlds, New Horizons in Astronomy and Astrophysics
– 2012 Report of the Subcommittee on Future Projects of High Energy Physics (Japan)
– 2013 European Strategy for Particle Physics Report
– 2013 U.S. Particle Physics Community-driven “Snowmass” process
o The timeline of processes that impact the next strategic plan:
– 2018-20: New NAS Astronomy and Astrophysics Decadal Survey
– 2019: Start of European Strategy for Particle Physics process
– 2019/20: Anticipated Japanese decision on ILC
– 2020: Release of updated European Strategy for Particle Physics
– 2020: Earliest opportunity for National Science Board to approve obligating MREFC
for HL-LHC
o New Snowmass Process will be officially inaugurated at the 2020 April APS Mtg.
o Yearlong sequence of workshops culminating in a 10-day Summer Study in 2021

8/1/19 P. Cushman and Y-K Kim DPF 2019 30Physics Groups and Cross-cutting Groups
Our first task is to determine a complete set of physics and cross-cutting topics.
The new topics define the working groups and final summary papers (in ArXiv)
as well as generating multiple white papers
We need to be broader than Funding Agency boundaries.
P5 can always draw a stricter boundary after we have done our work
e.g. 0nbb, gravitational waves, gamma ray astrophysics.
DPF will be joined by subsets of DAP, DPB, DNP, DGRAV, DCOMP
Important to define the science overlap that is specific to particle physics
2013 was organized according to Energy, Cosmic, Intensity Frontier
We need continuity, but we can evolve
e.g. Intensity may split into 2 groups and 0nbb might join neutrinos
P5 can always package them together later if needed
New cross-cutting groups and new computational categories
Theory will have its own frontier, but phenomenology will be unified with
experiment and liaisons between the two identified.
8/1/19 P. Cushman and Y-K Kim DPF 2019 31Need a long term sustainable web/wiki platform
Huh????
8/1/19 P. Cushman and Y-K Kim DPF 2019 32ENGAGE is maintained by APS, but not ready In the meantime, we will explore using SLACK (FNAL) as our primary community discussion platform. Look for an announcement when ready. APS will also provide some resources for workshop coordination e.g. registration tools, code of conduct, disability accommodation, TBD 8/1/19 P. Cushman and Y-K Kim DPF 2019 33
Draft Timeline for Snowmass 2021
DPF Program committee is currently reviewing the old topics
https://www.aps.org/units/dpf/governance/committees/program.cfm
Late August: Begin the process of community involvement on new draft topics
Call for site selection proposals for summer 2021
October: Finalize topics and cross-cutting categories.
DPF Exec will establish detailed job descriptions for co-conveners
Program Committee will accept nominations, collate recommendations
and submit to DPF Exec for convener selection
Sub-conveners will also be selected by DPF exec, after convener nomination
Spring 2020: Secure funding for workshops and overall plan
Choose 2021 site, date, and duration
Spring 2020 – Spring 2021: Conduct workshops, prepare initial white papers
Summer 2021: Snowmass Summer Study Final Collation
Report due by December 2021
