Split symmetries
We consider six-dimensional supergravity with gauge group SO(10)×U(1)A, compactified on the orbifold T2/Z2. Three quark–lepton generations arise as zero modes of a bulk 16-plet due to magnetic flux of the anomalous U(1)A. Boundary conditions at the four fixed points break SO(10) to subgroups whose i...
