> Possible ways to see or find particles that represent dark matter and create gamma rays:-http://www.scientificamerican.com/article/galactic-signal-boosts-lhc-s-dark-matter-search/?WT.mc_id=SA_WR_20150506-"In 2009, Hooper and Lisa Goodenough, then a graduate student at New York University, were the first to spot the signal, in data from NASA&apos;s Fermi Gamma-Ray Space Telescope. They proposed that the bump was a signature of dark matter. Two colliding dark-matter particles would annihilate each other, just as ordinary matter does with antimatter. The annihilation would generate a succession of short-lived particles that would eventually produce ?-rays.-"But the proposed particle, which has been dubbed the hooperon or gooperon after its proponents, soon ran into problems with physicists&apos; favourite version of supersymmetry. Although the minimal supersymmetric standard model (MSSM) allows for dark-matter particles with the estimated mass of hooperons&#151;about 25-30 gigaelectronvolts (1 GeV is roughly the mass of a proton)&#151;multiple experiments had suggested that the particles must be heavier. To accommodate hooperons, MSSM would have to be modified to an extent that makes many physicists uncomfortable. &#147;It would have required a completely new theory,&#148; says Sascha Caron, a particle physicist at Radboud University Nijmegen in the Netherlands, who leads the team behind the latest calculations.-*****-"Armed with this insight, Caron and his collaborators recalculated the predictions of the MSSM theory and found another potential explanation for the excess&#151;an existing dark-matter candidate called a neutralino. The neutralino was heavy enough not to be excluded by previous experiments, yet light enough to potentially be produced in the second run of the LHC.-"Caron&apos;s model also produces a prediction for the amount of dark matter that should have been created in the Big Bang that is compatible with state-of-the-art observations of the cosmic microwave background&#151;the relic radiation of the Big Bang&#151;performed by the European Space Agency&apos;s Planck probe (see Nature http://doi.org/38k; 2014). This cannot be a coincidence, he says. &#147;I find this quite amazing.&apos;&#148;-They might be on to something. The LHC has a chance of finding a piece of the puzzle.
