The next few decades could be one of the most exciting periods in the history of physics. One of the great scientific achievements of the 20th century was the development of the Standard Model of elementary particle physics, which describes the relationships among the known elementary particles and the characteristics of three of the four forces that act on those particles -- electromagnetism, the strong force, and the weak force (but not gravity)

program in elementary particle physics is at a crossroads.

From page 7... ...
The U.S. program in elementary particle physics should be characterized by a commitment to leadership within the global particle physics enterprise.

From page 8... ...
A broad array of scientific opportunities exists in elementary particle physics, and it is not possible to foretell which will yield important new results soonest. Two of the greatest discoveries of the last decade -- those of nonzero neutrino masses and dark energy -- were quite unexpected and arose from experiments that did not use accelerators, the tools characteristic of many other advances in particle physics.

A standing national committee is needed that has sufficient authority to establish a compelling set of priorities and to advise the federal agencies that support particle physics. Such a committee should evaluate the merits of specific proposals and make recommendations regarding the national particle physics program within the context of the

The most compelling current scientific opportunity in elementary particle physics is exploration of the Terascale, and this is the committee's highest priority for the U.S. program.

From page 11... ...
national effort in elementary particle physics should be to continue as an active partner in realizing the physics potential of the LHC experimental program. The LHC will be the center of gravity for elementary particle physics over at least the next 15 years as it explores the new phenomena expected to exist at the Terascale.

From page 12... ...
Although site selection for the ILC will be determined through an interna tional process, the existing physical infrastructure and human capital at Fermilab make it an advantageous site within the United States. As the only national labora tory devoted primarily to particle physics, Fermilab has an opportunity and a responsibility to the national particle physics program to secure the ILC as its top priority.

elementary particle physics re search budget should be allocated to the three research challenges articu lated below. Three major research challenges in astrophysics and cosmology research could lead to discoveries with potentially momentous implications for particle physics: · The direct detection of dark matter in terrestrial laboratories, the results of which could then be combined with measurements of candidate dark mat ter particles produced in accelerators.

From page 14... ...
U.S. participation in large-scale, high-precision experiments that probe particle physics beyond the Standard Model should continue, but the level of support that can be sustained will have to be very sensitive to the overall budget picture.
|
From page 15... ...
By committing to a strategic vision in particle physics, the United States can remain a leader in this vital area of science and technology.
