DESCRIPTION:Solutions of string/M theory with low energy super
 symmetry have moduli fields with masses which are 
 generically of order the mass of the gravitino. Th
 is leads to a spectrum of superpartners with squar
 ks and sleptons just beyond the LHC energy scale. 
 Gluinos could however be produced at the LHC and d
 ecay with top and bottom rich final states. The ma
 ss of the lightest Higgs boson is predicted to be 
 between 122 and 129 GeV. The moduli fields dominat
 e the pre-BBN Universe leading to a non-thermal hi
 story which significantly impacts our picture of d
 ark matter\, which is predicted to have two compon
 ents: axions and W-ino like WIMPS. The tentative h
 igh energy photon signal in the Fermi-LAT data can
  be successfully interpreted as the annihilation o
 f these WIMPs into the Z-boson and a photon. Moreo
 ver\, we demonstrate that this signal is also cons
 istent with an approximately 50% axion component. 
 The axion component implies that experiments like 
 Planck will NOT observe tensor modes in the CMB.\n
