Biased Discrete Symmetry Breaking and Fermi Balls
The spontaneous breaking of an approximate discrete symmetry is considered, with the resulting protodomains of true and false vacuum being separated by domain walls. Given a strong, symmetric Yukawa coupling of the real scalar field to a generic fermion, the domain walls accumulate a gas of fermions, which modify the domain wall dynamics. The splitting of the degeneracy of the ground states res...
متن کاملSupersymmetry breaking and Fermi balls.
The possibility exists that the early universe experienced a sequence of symmetry breaking phase transitions, which could have resulted in the production of defects, such as monopoles, cosmic strings, or domain walls [1–3]. Furthermore, it is possible that supersymmetry could have been physically realized during early epochs, becoming broken after defect formation, at a lower energy scale. It i...
متن کاملDiscrete Symmetry and GUT Breaking
We study the supersymmetric GUT models where the supersymmetry and GUT gauge symmetry can be broken by the discrete symmetry. First, with the ansatz that there exist discrete symmetries in the branes’ neighborhoods, we discuss the general reflection Z2 symmetries and GUT breaking on M 4 × M1 and M4 × M1 × M1. In those models, the extra dimensions can be large and the KK states can be set arbitr...
متن کاملSUSY Glue-Balls, Dynamical Symmetry Breaking and Non-Holomorphic Potentials
We discuss the instability of the Veneziano-Yankielowicz effective action (or its supersymmetric ground-state) with respect to higher order derivative terms. As such terms must be present in an effective action, the V-Y action alone cannot describe the dynamics of SYM consistently. We introduce an extension of this action, where all instabilities are removed by means of a much richer structure ...
متن کاملRenormalization, Symmetry Breaking, and Discrete Scale Invariance
One of the most basic applications of quantum mechanics is the study of a two body system with a spherically symmetric interaction. This problem is characterized simply by giving the mass of each particle as well as the inter-particle potential V (r) which is a function of the inter-particle separation only. This problem can be reduced in a straightforward way to a simpler one particle problem ...
