NEW PHYSICS IN A NUTSHELL, OR Q-BALL AS A POWER-PLANT

Future experiments may discover new scalar particles with global charg es acid couplings that allow for solitonic states. If the effective po tential has flat directions, the scalar VEV inside a large Q-ball can exceed the particle mass by many orders of magnitude. Models with low- energy supersymmetry breaking generically have both the scalars carryi ng some global charges, and the flat directions. The Q-ball interior c an, therefore, provide an environment for exploring physics far beyond the TeV scale without the need for building colliders of ever-increas ing energies. Some Standard Model processes, otherwise strongly suppre ssed, can also be studied inside the soliton, where the SU(2) symmetry can be restored, and the quark confinement may be absent. Baryon numb er violating processes catalyzed by the large VEV inside the e-ball ca n provide an inexhaustible energy resource. (C) 1998 Elsevier Science B.V.
