Chiral low-energy physics from squashed branes in deformed \( \mathcal{N}=4 \) SYM

Open Access
Regular Article - Theoretical Physics


We discuss the low-energy physics which arises on stacks of squashed brane solutions of SU(N ) \( \mathcal{N}=4 \) SYM, deformed by a cubic soft SUSY breaking potential. A brane configuration is found which leads to a low-energy physics similar to the standard model in the broken phase, assuming suitable VEV’s of the scalar zero modes. Due to the triple self-intersection of the branes, the matter content includes that of the MSSM with precisely 3 generations and right-handed neutrinos. No exotic quantum numbers arise, however there are extra chiral superfields with the quantum numbers of the Higgs doublets, the W, Z, eR and uR, whose fate depends on the details of the rich Higgs sector. The chiral low-energy sector is complemented by a heavy mirror sector with the opposite chiralities, as well as super-massive Kaluza-Klein towers completing the \( \mathcal{N}=4 \) multiplets. The sectors are protected by two gauged global U(1) symmetries.
