Generic String/M theory Predictions for Particle Physics and Dark Matter

Mathematics and Applications of Branes in String and M-theory
Solutions of string/M theory with low energy supersymmetry have moduli fields with masses which are generically of order the mass of the gravitino. This leads to a spectrum of superpartners with squarks and sleptons just beyond the LHC energy scale. Gluinos could however be produced at the LHC and decay with top and bottom rich final states. The mass of the lightest Higgs boson is predicted to be between 122 and 129 GeV. The moduli fields dominate the pre-BBN Universe leading to a non-thermal history which significantly impacts our picture of dark matter, which is predicted to have two components: axions and W-ino like WIMPS . The tentative high energy photon signal in the Fermi-LAT data can be successfully interpreted as the annihilation of these WIM Ps into the Z-boson and a photon. Moreover, we demonstrate that this signal is also consistent with an approximately 50% axion component. The axion component implies that experiments like Planck will NOT observe tensor modes in the CMB .
