In the Planck Model, broken symmetries are manifested on the mass levels of the three Planck sequences. Superpartners, resulting from the breaking of supersymmetry, are arranged symmetrically about superlevels within each sequence. There are two types of superlevel: every third level in each sequence (Type 1) and every fifth level in each sequence (Type 2). The superpartners of each charged lepton and quark are identified; the superpartnerships are centred on superlevels of Type 1. The electron, the up quark and, intriguingly, the proton participate in superpartnerships that are symmetrically arranged about coincident superlevels of Type 1. The W and Z weak gauge bosons and the 126 GeV Higgs boson participate in a trio of superpartnerships about three coincident superlevels of Type 2. Coincident superlevels are rare, concentrated at known particle mass scales, and lie in a symmetric pattern that results from the interplay of the Planck sequences. The pattern of coincident superlevels extends from the GUT scale to meV scale, forming the background to the see-saw mechanism of neutrino mass generation.
