Abstract: (Elsevier)
A large family of field theories in 3 + 1 dimensions contains a new class of extended objects. The existence of these objects depends on (among other conditions) the existence of a conserved charge, Q , associated with an ungauged unbroken continuous internal symmetry. These objects are spherically symmetric, and for large Q their energies and volumes grow linearly with Q ; thus they act like homogeneous balls of ordinary matter, with Q playing the role of particle number. This paper proves the fundamental existence theorem for these Q-balls, computes their elementary properties, and finds their low-lying excitations.- FIELD THEORY: SCALAR
