摘要

摘要

En 中文
We obtain Q-ball solutions in noncommutative scalar field theory with a global U(1) invariance. The Q-ball solutions are shown to be classically and quantum mechanically stable. We also find that excited Q-ball states exist for some class of scalar potentials, which are classically stable in the large noncommutativity limit. (C) 2001 Published by Elsevier Science B.V.
