1. Rough estimate of cost and schedule

  2. Description of the science questions that will be addressed and, to the extent possible, the science reach

  3. Discussion of plans for or potential/need for multi-agency involvement

Based upon the information received, the CPU will invite presentations of projects that have significant potential to address our 11 science questions at upcoming CPU meetings associated with the APS April meeting in Washington, DC, the AAS June meeting in Pasadena, the Snowmass meeting in July and further meetings to be announced.

The Phase I report will be presented at a public session at the April APS meeting and members of the CPU will be present to answer questions and receive comments. The following are the 11 science opportunities identified in “Connecting Quarks with the Cosmos:”

  • What is the dark matter?

  • What are the masses of the neutrinos, and how have they shaped the evolution of the universe?

  • Are there additional space-time dimensions?

  • What is the nature of the dark energy?

  • Are protons unstable?

  • How did the universe begin?

  • Did Einstein have the last word on gravity?

  • How do cosmic accelerators work and what are they accelerating?

  • Are there new states of matter at exceedingly high density and temperature?

  • Is a new theory of matter and light needed at the highest energies?

  • How were the elements from iron to uranium made?

A more complete description of the questions and their context is contained in the Phase I report (available at http://www.nas.edu/bpa/reports/cpu/index.html).
