Discrete Gauge Symmetry and Aharonov-Bohm Radiation in String Theory
Yutaka Ookouchi
We investigate cosmological constraints on phenomenological models with discrete gauge symmetries by discussing the radiation of standard model particles from Aharonov-Bohm strings…
More on cosmological constraints on spontaneous R-symmetry breaking models
Yuta Hamada, Kohei Kamada, Tatsuo Kobayashi +1
We study the spontaneous R-symmetry breaking model and investigate the cosmological constraints on this model due to the pseudo Nambu-Goldstone boson, R-axion. We consider the R-ax…
Cosmic R-string in thermal history
Kohei Kamada, Tatsuo Kobayashi, Keisuke Ohashi +1
We study stabilization of an unstable cosmic string associated with spontaneously broken symmetry, which otherwise causes a dangerous roll-over process. We demonstrate tha…
Instability of colliding metastable strings
Takashi Hiramatsu, Minoru Eto, Kohei Kamada +2
The breaking of symmetry plays a crucial role in modeling the breaking of supersymmetry (SUSY). In the models that possess both SUSY preserving and SUSY breaking vacua, tu…
