We obtain a new type of a stable Q ball in the context of gauge-mediated supersymmetry breaking in minimal supersymmetric standard model. It is so-called gravity-mediation type of Q ball, but stable against the decay into nucleons, since the energy per unit charge is equal to gravitino mass m_{3/2}, which can be smaller than nucleon mass in the gauge-mediation mechanism. We consider the cosmological consequences in this new Q-ball scenario, and find that this new type of the Q ball can be considered as the dark matter and the source for the baryon number of the universe simultaneously.

    hep-th 2019-08 conditional novelty 7.0 of 10

    The paper shows that generalized scalar weak gravity conjectures imply the parameter conditions for early-universe scalar condensates to fragment into solitonic lumps, which could form dark matter or primordial black holes.

    Hartree quantum fluctuations in 3+1D simulations of the Friedberg-Lee-Sirlin model produce a regime where fluctuations carry significant Noether charge, periodic charge exchange occurs, and some classically stable Q-b...

    3+1D lattice simulations show PQ-balls form from a rotating complex scalar and decay faster for stronger symmetry breaking, with lifetimes roughly scaling as v^4.

    A comprehensive review of non-topological solitons (Q-balls) and quasi-solitons (oscillons), their properties, dynamics, and roles in early-universe physics.
