SUMMARY:Detecting Ultrashort Gamma-ray Bursts Originated from Ultrahea
 vy Dark Matter Collisions\, Theory Seminar (High Energy/Cosmology)\, X
 uheng Luo\, Johns Hopkins University
DESCRIPTION:Dark matter may exist today in the form of ultraheavy comp
 osite bound states. Collisions between such dark matter states can rel
 ease intense bursts of gamma-rays. Thus\, indirect-detection signals o
 f dark matter may include unconventional gamma-ray bursts. Such bursts
  may have been missed not necessarily because of their low arriving ga
 mma-ray fluxes\, but rather their ultrashort duration and rareness.
\n
  
\nIn this talk\, I will discuss the strategies and prospects for det
 ecting such ultrashort gamma-ray burst. I will also present a concrete
  dark matter model that produces bursts potentially detectable by the 
 current instruments.
