Particle physics research in the United States has
been a vibrant field since the middle of the past century.
In the past thirty years the particle physics
community has gathered periodically at Snowmass, Colorado, to
take stock of its progress and chart its future. The
last such meeting was held in
2001.
The 2013 Community Summer Study was held on the campus
of the University of Minnesota, July 29 to
August 6, 2013. It was designed to
address the questions the particle physics community wishes to answer
over the
next two decades, and how we plan to answer them. While we did not prioritize
activities, our aim
was to ask and answer hard questions. Our aim has been to
produce a resource book, of length and emphasis
similar to the
Physics Briefing Book of the European Strategy Group, which will convey the
health and diversity
of the U.S. program, in a global context, to our colleagues
and fellow citizens. Although we found it convenient
to retain the
"frontier" categories of the previous Particle Physics Project Prioritization Panel (P5), whose
last
report was issued in 2008, the division of the field into such categories should not obscure
our focus on
fundamental questions of physics, which, by their nature, cross such frontiers.
These inter-frontier discussions
were a major component of the meeting in Minneapolis.
These proceedings are organized as follows: The
Summary lays out the broad topics that were addressed during
the workshop and
presented the major conclusions. This 50-page document contains a 7-page
Executive Summary.
Following this, there is a web page for each Frontier —
Intensity, Energy, Cosmic, Theory, Accelerator Capabilities,
Underground
Capabilities, Instrumentation, Computing, and Communication, Education, and
Outreach. Each of these
pages links to a summary report for the Frontier, the
report of each of the Frontier working groups, and all White
Papers contributed
to the discussion of that Frontier. The final link provides an 18-page Glossary
of acronyms and
identifiers for the study.
The major reports from Snowmass have been issued together in book form:
FERMILAB-CONF-13-648, SLAC-PUB-15960.
The pdf file for the book is available at
