  These reports present the results of the 2013 Community Summer Study of the
APS Division of Particles and Fields ("Snowmass 2013") on the future program of
particle physics in the U.S. Chapter 2, on the Intensity Frontier, discusses
the program of research with high-intensity beams and rare processes. This area
includes experiments on neutrinos, proton decay, charged-lepton and quark weak
interactions, atomic and nuclear probes of fundamental symmetries, and searches
for new, light, weakly-interacting particles.
