Cancellation of anomalies in supersymmetric sigma models based on exceptional groups
TL;DR: In this article, it was shown that there is no global obstruction in the supersymmetric E 8 /SO(10)×U(1) 3 sigma model which accomodates three families of ordinary quarks and leptons and one mirror family as quasi-Nambu-Goldstone fermions.
Gamma rays and positrons from a decaying hidden gauge boson
TL;DR: In this paper, the authors studied a scenario that a hidden gauge boson constitutes the dominant component of dark matter and decays into the standard model particles through a gauge kinetic mixing.
Complete solution to the strong C P problem: Supersymmetric extension of the Nelson-Barr model
TL;DR: In this article, a supersymmetric solution to the strong $CP$ problem based on spontaneous $CP-violation is presented. But the solution does not address the effects coming from supersymmetry breaking.
Gauged Peccei-Quinn Symmetry - A Case of Simultaneous Breaking of SUSY and PQ Symmetry
TL;DR: In this article, the authors apply the gauged Peccei-Quinn (PQ) mechanism to models where the global PQ symmetry and supersymmetry (SUSY) are simultaneously broken at around O(10^{11-12})$,GeV.
NANOGrav Results and LIGO-Virgo Primordial Black Holes in Axionlike Curvaton Models.
TL;DR: In this article, the axion-like curvaton model was used to explain the LIGO-Virgo events and the NANOGrav results simultaneously, and it was shown that the inevitable non-Gaussianity of this model suppresses the induced GWs associated with primordial black holes associated with PBHs.
