extends the MSSM gauge group by a U (1)′ symmetry, which is broken at low energy …

Freeze-in bino dark matter in high-scale supersymmetry

C Han, P Wu, JM Yang, M Zhang - Physical Review D, 2024 - APS
We explore a scenario of high-scale supersymmetry where all supersymmetric particles

which the nonuniversal boundary conditions are imposed at MGUT. Even though the …

Supersymmetric and the weak gravity conjecture

A Pal, Q Shafi - Physical Review D, 2019 - APS
The gauge symmetry SU (5)× U (1) χ is the unique maximal subgroup of SO (10) which
retains manifest unification at MGUT of the Standard Model gauge couplings, especially if …

Low fine-tuning with heavy higgsinos in Yukawa unified SUSY GUTs

Stop search in SUSY SO (10) GUTs with nonuniversal Gaugino masses

Z Altın, Z Kırca, T Tanımak, C Salih Ün - The European Physical Journal C, 2020 - Springer
