SUMMARY:Generic String/M theory Predictions for Particle Physics and Dark 
 Matter - Acharya\, B (Abdus Salam International Centre for Theoretical Phy
 sics)

DESCRIPTION:Solutions of string/M theory with low energy supersymmetry hav
 e moduli fields with masses which are generically of order the mass of the
  gravitino. This leads to a spectrum of superpartners with squarks and sle
 ptons 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 th
 e lightest Higgs boson is predicted to be between 122 and 129 GeV. The mod
 uli fields dominate the pre-BBN Universe leading to a non-thermal history 
 which significantly impacts our picture of dark matter\, which is predicte
 d 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 WIMPs into the Z-boson and a photon. Moreove
 r\, we demonstrate that this signal is also consistent with an approximate
 ly 50% axion component. The axion component implies that experiments like 
 Planck will NOT observe tensor modes in the CMB.\n\n
