Probing Supersymmetry Breaking Scale with Atomic Clocks
arXiv:2209.03231 · doi:10.1016/j.nuclphysb.2023.116260
Abstract
The supersymmetry (SUSY) breaking mechanism generally predicts the existence of the sgoldstinos, which can play the role of wave-like dark matter. Due to the ubiquitous coupling to the electromagnetic fields, the light scalar sgoldstino dark matter can lead to the variance of the fine-structure constant. With the precise atomic clock data, we find the SUSY breaking scale can be probed up to the GUT scale in the sgoldstino mass range of eV eV.
