Advisory panel issues field-defining recommendations for investments in particle physics research

Argonne is set to contribute to the realization of the recommendations, which will shape the next decade of discovery in particle physics

( Contributions from Argonne will drive innovation in particle physics and shed light on outstanding mysteries in the field.

Yesterday marked the release of a highly anticipated report from the Particle Physics Project Prioritization Panel (P5), unveiling an exciting new roadmap for unlocking the secrets of the cosmos through particle physics.

The report was released by the High Energy Physics Advisory Panel to the High Energy Physics program of the Office of Science of the U.S. Department of Energy (DOE) and the National Science Foundation’s Division of Physics. It outlines particle physicists’ recommendations for research priorities in a field whose projects — such as building new accelerator facilities — can take years or decades, contributions from thousands of scientists and billions of dollars

The 2023 P5 report represents the major activity in the field of particle physics that delivers recommendations to U.S. funding agencies. This year’s report builds on the output of the 2021 Snowmass planning exercise — a process organized by the American Physical Society’s (APS) Division of Particles and Fields that convened particle physicists and cosmologists from around the world to outline research priorities. This membership division constitutes the only independent body in the U.S. that represents particle physics as a whole.

“With our state-of-the-art facilities and community of dedicated scientists, Argonne’s contributions are shaping the global trajectory of high-energy physics.” — Rik Yoshida, Argonne High Energy Physics Division Director

“The P5 report will lay the foundation for a very bright future in the field,” said R. Sekhar Chivukula, 2023 chair of the APS Division of Particles and Fields and a distinguished professor of physics at the University of California, San Diego. ​“There are extraordinarily important scientific questions remaining in particle physics, which the U.S. particle physics community has both the capability and opportunity to help address, within our own facilities and as a member of the global high energy physics community.”

The report includes a range of budget-conscious recommendations for federal investments in research programs, the U.S. technical workforce and the technology and infrastructure needed to realize the next generation of transformative discoveries related to fundamental physics and the origin of the universe. For example, the report recommends continued support for the Deep Underground Neutrino Experiment (DUNE), based out of DOE’s Fermilab in Illinois, for CMB-S4, a network of ground-based telescopes designed to observe the cosmic microwave background (CMB), and for the planned expansion of the South Pole’s neutrino observatory, an international collaboration known as IceCube-Gen2, in a facility operated by the University of Wisconsin–Madison.

Researchers at DOE’s Argonne National Laboratory stand at the forefront of high energy physics and are poised to contribute significantly to the advancement of the field over the next decade. They are exploring the fundamental nature of the universe and pioneering innovative technologies with far-reaching implications. In particular, Argonne’s High Energy Physics (HEP) division leverages the laboratory’s suite of multidisciplinary facilities and equipment — including world-class scientific computing capabilities — to further scientific discovery and advance accelerator technology. For example, Argonne’s contributions to key high energy physics collaborations include the design and fabrication of components for DUNE, the development of cutting-edge detectors for CMB-S4 and more.

“With our state-of-the-art facilities and community of dedicated scientists, Argonne’s contributions are helping to shape the global trajectory of high-energy physics,” said Rik Yoshida, director of Argonne’s HEP division. ​“This report reflects the collective wisdom of the high energy physics community, and we look forward to leveraging our expertise and capabilities here at Argonne to help uncover the mysteries of the universe, drive innovation, inspire future generations of scientists and bolster our nation’s vital role in the future of particle physics.”

“In the P5 exercise, it’s really important that we take this broad look at where the field of particle physics is headed, to deliver a report that amounts to a strategic plan for the U.S. community with a 10-year budgetary timeline and a 20-year context. The panel thought about where the next big discoveries might lie and how we could maximize impact within budget, to support future discoveries and the next generation of researchers and technical workers who will be needed to achieve them,” said Karsten Heeger, P5 panel deputy chair and Eugene Higgins Professor and chair of physics at Yale University.

New knowledge, and new technologies, set the stage for the most recent Snowmass and P5 convenings. ​“The Higgs boson had just been discovered before the previous P5 process, and now our continued study of the particle has greatly informed what we think may lie beyond the standard model of particle physics,” said Hitoshi Murayama, P5 panel chair and the MacAdams Professor of physics at the University of California, Berkeley. ​“Our thinking about what dark matter might be has also changed, forcing the community to look elsewhere — to the cosmos. And in 2015, the discovery of gravitational waves was reported. Accelerator technology is changing too, which has shifted the discussion to the technology R&D needed to build the next-generation particle collider.”

The U.S. participates in several major international scientific collaborations in high energy physics and cosmology, including the European Council for Nuclear Research (CERN), which operates the Large Hadron Collider, where the Higgs boson was discovered in 2012. The P5 report recommends that the U.S. support a significant in-kind contribution to a new international facility, the ​“Higgs factory,” to further our understanding of the Higgs boson.

It also recommends that the U.S. study the possibility of hosting the next most-advanced particle collider facility to reinforce the country’s leading role in international high energy physics for decades to come.

Activities of the P5 are supported in part by the APS’s Division of Particles and Fields.

Study reveals Zika’s shape-shifting machinery—and a possible vulnerability

Study reveals Zika’s shape-shifting machinery—and a possible vulnerability
Viruses have limited genetic material—and few proteins—so all the pieces must work extra hard. Zika is a great example; the virus only produces 10 proteins. Now, in a study published in the journal PLOS Pathogens, researchers at Sanford Burnham Prebys have shown how the virus does so much with so little and may have identified a therapeutic vulnerability.   In the study, the research team showed that Zika’s enzyme—NS2B-NS3—is a multipurpose tool with two essential functions: breaking up proteins (a protease) and dividing its own double-stranded RNA into single strands (a helicase).   “We found that Zika’s ...

Genetic mutations that promote reproduction tend to shorten human lifespan, study shows

    A University of Michigan-led study based on a review of genetic and health information from more than 276,000 people finds strong support for a decades-old evolutionary theory that sought to explain aging and senescence.   In 1957, evolutionary biologist George Williams proposed that genetic mutations that contribute to aging could be favored by natural selection if they are advantageous early in life in promoting earlier reproduction or the production of more offspring. Williams was an assistant professor at Michigan State University at ...

A dynamic picture of how we respond to high or low oxygen levels

A dynamic picture of how we respond to high or low oxygen levels
SAN FRANCISCO—December 8, 2023—It only takes holding your breath for slightly too long to understand that too little oxygen is bad for you. But can you also have too much? Indeed, breathing air with a higher oxygen level than your body needs can cause health problems or even death.   But with scant research on the topic, scientists have known little about how the body senses too much oxygen. Now, a new study from Gladstone Institutes has greatly expanded the scientific body of knowledge about the mechanisms at play, and why it matters for health. Their findings, reported in the journal Science Advances, explain how breathing air with different levels of ...
