SUMMARY:Searching for Q-balls with the High Altitude Water Cherenkov O
 bservatory\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Peter Karn\, 
 UC Irvine
DESCRIPTION:The High Altitude Water Cherenkov (HAWC) Observatory is a 
 gamma-ray experiment currently under construction at Sierra Negra in M
 exico. When complete it will consist of a 22\,000 square meter array o
 f 300 water Cherenkov detectors. Although HAWC is designed to study ga
 mma rays from galactic and extra-galactic sources\, the large volume o
 f instrumented water (each tank holds ~188\,000 liters) gives the oppo
 rtunity to search for rare objects. One such target is the Q-ball\, a 
 very massive\, subrelativistic particle that can have a large baryon n
 umber and can be stable since their creation in the early universe. If
  stable\, Q-balls would make up some of the dark matter of the univers
 e\, but their large mass means their flux is very low. HAWC has a flex
 ible data acquisition system which\, with a dedicated trigger algorith
 m for non-relativistic species\, allows a search for Q-balls traversin
 g the detector.  The Q-ball trigger\, simulation\, and analysis will b
 e presented.
