Quark and lepton mass matrices from localization in M-theory on $G_2$ orbifold

26 Feb 2020 Eric Gonzalez Gordon Kane Khoa Dang Nguyen Malcolm J. Perry

M-theory compactified on a $G_2$ manifold with resolved $E_8$ singularities realizes 4d $\mathcal{N} = 1$ supersymmetric gauge theories coupled to gravity with three families of Standard Model fermions. Beginning with one $E_8$ singularity, three fermion families emerge when $E_8$ is broken by geometric engineering deformations to a smaller subgroup with equal rank... (read more)
