ALPHA MAGNETIC SPECTROMETER • A landmark experiment • Scheduled for launch in April to the International Space Station • Can AMS-02 disentangle dark matter from pulsars? Pato, Lattanzi, Bertone (2010) 23 Mar 11 Feng 16
DIRECT DETECTION • Can look for normal matter recoiling from DM collisions • WIMP properties – m ~ 100 GeV – velocity ~ 10 -3 c – Recoil energy ~ 1-100 keV • Typically focus on ultrasensitive detectors placed deep underground • But first, what range of interaction strengths are possible to investigate? 23 Mar 11 Feng 17 DM
