New HEPAP Report Outlines Revolution in Particle Physics

Washington, DC - The most compelling questions facing contemporary
particle physics research and a program to address them have been
distilled into a new report “Quantum Universe: The Revolution in
21st-Century Particle Physics,” adopted today by the Department of
Energy/National Science Foundation High Energy Physics Advisory Panel
(HEPAP).

The discovery  that the universe is made mostly of unknown forms of
matter and energy called  “dark matter” and “dark energy” has
revolutionized the scientific outlook for particle physics, astrophysics
and cosmology.  The “Quantum Universe” report responds to a November
request to HEPAP from DOE and NSF  for a report that “will illuminate
the issues and provide a clear picture of the connected, complementary
experimental approaches to the truly exciting scientific questions of
this century.”

A HEPAP subcommittee led by Stanford Linear Accelerator Center Research
Director Persis Drell produced the report. “Quantum Universe” identifies nine defining scientific questions in three areas:

Einstein’s Dream of Unified Forces
1. Are there undiscovered principles of nature: new symmetries, new
physical laws?
2. How can we solve the mystery of dark energy?
3.  Are there extra dimensions of space?
4.  Do all the forces become one?

The Particle World
5.  Why are there so many kinds of particles?
6. What is dark matter?  How can we make it in the laboratory?
7.  What are neutrinos telling us?

The Birth of the Universe
8. How did the universe come to be?
9. What happened to the antimatter?

“‘Quantum Universe’ discusses how the combined evidence from existing
and future accelerators, underground laboratories, space probes and
ground-based telescopes will help us answer these questions and
profoundly change our understanding of the fundamental nature of the
universe,” Drell said.
