Dark dimension and the standard model landscape

LA Anchordoqui, I Antoniadis, J Cunat - Physical Review D, 2024 - APS

Searching for supersymmetry: the μνSSM: A short review

DE López-Fogliani, C Munoz - The European Physical Journal Special …, 2020 - Springer
We review the role played by the 'μ from ν'supersymmetric standard model (μν SSM) in the
search for supersymmetry. First, we discuss its theoretical motivation, that is the …
