Primordial Lithium Problem: The Future

• observational solution? test with extragalactic Li observations
  • LiH toward B0218+357 (Friedel, Kemball, BDF 2011)
  • atomic Li in the LMC (Howk+ 2012)
• new physics? e.g. SUSY

Particle Dark Matter

Particle Dark Matter: Relic Species

• production in the early universe
• annihilation freezeout
• the WIMP miracle

Particle Dark Matter: WIMP Searches

• Accelerators: Tevatron and CDF at Fermilab,
  LHC and ATLAS at CERN,
  
• Direct searches: CDMS: detector, fridge and icebox at the Soudan mine; interesting recent results
  DAMA new detector installation at Gran Sasso
  CRESST
  CoGeNT
  SuperCDMS
  LUX
  the current state of the art
  
• Indirect (astrophysical) searches
  • cosmic rays: positrons
    PAMELA: excess positron fraction
    ATIC: excess e⁺+e^-
    but Fermi begs to differ
  • gamma-rays
    HESS TeV photons from the Galactic center
    Fermi/GLAST opens a new window on the GeV-TeV sky
