Why particle physics matters

Particle physics has revolutionized the way we look at the universe. Along the way, it's made significant impacts on other fields of science, improved daily life for people around the world and trained a new generation of scientists and computing professionals. Image: Sandbox Studio

As the lights came on and the camera started to roll, Heidi Schellman took a deep breath, collected her thoughts and began: "Hello, I'm Heidi Schellman and I'm a high-energy physicist working at Northwestern University. What effect does my research have on you?"

Particle physics research has brought about revolutions in our understanding of the world around us, she explained. But scientific exploration is more than just its own reward.

"When physicists start to measure new things, there is no catalog to order the equipment from. We make it ourselves," she said.

"An analogy might be an expedition climbing Mount Everest. Is someone climbing Everest useful to you in everyday life? Not at first glance, no matter how interesting it is for its own sake. But fleece jackets and breathable waterproof fabrics were first developed for serious mountaineering expeditions and are now cheap and indispensable.

"That's what's great about humankind. We like a challenge … and the new tools we build for it have long-lasting value."

Schellman's explanation, recorded as part of the "Why particle physics matters" video project at the 2013 Snowmass Community Summer Study meeting in Minneapolis, expressed a few of the many reasons that particle physics is important.

The benefits of the field span everything from advancing humankind's understanding of the universe around us, to applications in other fields of science as well as daily life, to training the next generation of scientists.

In so many ways, particle physics' impacts go far beyond the laboratory and the textbook.

The Fermilab Veterans Day Celebration takes place this year on Monday, Nov. 11, in Kuhn Barn from 11:30 a.m. to 1:30 p.m. Veterans from all armed services are invited. Admission is $7. Reserve your tickets by Thursday, Nov. 7. Reservation information is on the Veterans Day Celebration poster. Tickets will also be sold at the door.

The catered celebration will include a guest talk by Eric Wentz of the United States Navy and a presentation by the East Aurora High School Color Guard.

In the News

Absence of evidence, or evidence of absence?

From The Economist, Nov. 2, 2013

Cosmology and particle physics — or at least, the popular versions of them — tend to the grandiose. The Higgs boson, recently discovered at CERN, Europe's particle-physics laboratory, is not just any old particle. To the despair of many physicists, it has been dubbed the "God particle". Books on cosmology promise to reveal the "fabric of the cosmos", while their academic authors discuss different flavours of a "theory of everything".

The reality, though, is more disappointing — or perhaps more exciting, depending on your point of view. Physicists have excellent, accurate theories to describe the behaviour of the matter that makes up atoms. But they also know that this matter constitutes less than 5 percent of the substance of creation. The remainder is split between "dark energy", a notional force assigned responsibility for the accelerating expansion of the universe, and "dark matter", ghostly stuff whose existence seems necessary to make sense of the arrangement of the heavens. Both are the subject of intense study, and both remain deeply mysterious.

On October 30 the team running the Large Underground Xenon (LUX) experiment, in a mine 1,500 metres below South Dakota, announced the results of their first three months spent hunting for dark matter: nothing. That is big news. It contradicts evidence from several other experiments, which offered hints that dark matter had been spotted. And LUX is the most sensitive dark-matter detector yet built.

Director's Corner

P5 at Fermilab

Fermilab Director
Nigel Lockyer

While this would normally be a "bye week" for my column, I wanted to take the chance to inform the entire laboratory community about this past weekend's meeting of the Particle Physics Project Prioritization Panel (P5). The panel, chaired by Steve Ritz from UC Santa Cruz, is charged with developing an updated strategic plan for the United States that can be executed over a 10-year period in support of a 20-year global vision for the field. The Fermilab-hosted P5 meeting, the first of three open meetings for the panel, focused on input from the 2013 Snowmass meeting, neutrino research and the international particle physics environment.

More than 200 physicists participated and presented and discussed many good ideas. Fermilab scientist Regina Rameika presented the consensus view from the lab's Science Priorities Working Group. This group has been working very hard over the last month to develop a set of recommendations, with input from the broader scientific staff, for Fermilab's role in an optimized particle physics program. The view presented to P5 focused on:

  • continued involvement in the LHC and its upgrades,
  • a full-scope LBNE experiment with a far detector deep underground at the Sanford Lab,
  • a reorientation of Project X toward the goal of delivering greater than 1 MW of beam power on day one of LBNE operations,
  • next-generation rare-decay experiments that will take place this decade,
  • select Cosmic Frontier experiments,
  • a short-baseline neutrino program that builds on liquid-argon time projection chamber technologies,
  • and future accelerator R&D efforts dictated by a global plan.

The theme of a global plan for particle physics and accelerators surfaced many times throughout the meeting — this topic is here to stay. The discussions on neutrinos emphasized the exciting physics opportunities that exist and how to exploit them. There was an open microphone session where the community had an opportunity to express its views on the future program, and many participants took that opportunity to share their views with the P5 committee.

The next face-to-face P5 meeting is from Dec. 2-4 at SLAC, and the final meeting is from Dec. 15-18 at Brookhaven, where Fermilab will present in greater detail its plans to upgrade its accelerator complex for the LBNE experiment. The final P5 report, which will represent the U.S. particle physics community's consensus roadmap recommendations for the next decade, is due in spring 2014 and will be delivered to HEPAP for review before it is officially submitted to the funding agencies.
