Q-balls in the Mssm
A Q-ball is a stable, charge Q soliton in a scalar field theory with a spontaneously broken global U(1) symmetry . The Q-ball solution arises provided the scalar potential V (φ) is such that V (φ)/|φ|2 has a minimum at non-zero φ. In the MSSM such solitons are necessarily part of the spectrum of the theory, as was first pointed out by Kusenko . This is due to the form of the MSSM scalar potenti...
متن کاملQ-balls in the MSSM
Non-topological solitons have been studied in a variety of models [1]. One particular type of such solitons, Q-balls [1,2], are present in the spectrum of a theory, whenever it satisfies the conditions outlined below. This class of theories includes the MSSM and other supersymmetric generalizations of the Standard Model. Surprisingly, the rich phenomenology associated with the solitonic sector ...
متن کاملSpinning Q-balls in the complex signum-Gordon model
Rotational excitations of compact Q-balls in the complex signum-Gordon model in 2+1 dimensions are investigated. We find that almost all such spinning Q-balls have the form of a ring of strictly finite width. In the limit of large angular momentum Mz their energy is proportional to |Mz|.

متن کاملQ-balls in Underground Experiments
In this paper we present some features of Q-balls and we discuss their interactions with matter, and their energy losses in the Earth, for a large range of velocities. These calculations are used to compute the fractional geometrical acceptance of the MACRO detector. Furthermore a systematic analysis of the energy losses of Q-balls in three types of detectors is investigated. More specifically ...
متن کاملCharge-swapping Q balls.
Q balls are nontopological solitonic solutions to a wide class of field theories that possess global symmetries. Here we show that in these same theories there also exists a tower of novel composite Q-ball solutions where, within one composite Q ball, positive and negative charges coexist and swap at a frequency lower than the natural frequency of an individual Q ball. These charge-swapping Q b...
