Low Entropy Symplectic Structure leading to Dark Matter

Low Entropy Symplectic Structure (LESS) leading to Dark Matter developes a model of the entropic structure of space in the very early universe. To minimize entropy, symplectic triangulation of ordinary 3-space at the Planck scale, can be ordered in a crystal-like structure with energy stored as tension in the intersecting D-Brane faces of domains of identical tetrahedra. It is conjectured that this structure and others that follow can be relatively stable. Such “realized” domains are initially limited in size only by other domains which together fill space. The breakdown of the metastable initial state leads to predictions of dark matter candidates with discrete masses in the µeV range. They have not been ruled out by existing experimental data. Three of these are axions or axion-like particles with masses 31.54, 104.07 and 184.67 µeV. Fields consistent with the symmetries involved are found in the NS+ NS+ sector of the Type IIB GSO projection of supersymmetric string theory. The theory can be modeled in a time slice with 3 spatial dimensions in either a 6-dimensionsl phase space or the full 10-dimensional string theory. Both are symplectic. Free parameters can be chosen to make the model consistent with early Slow Roll Inflation and the present stable halo structures.
