Dark Matter Limits from Dwarf Spheroidal Galaxies with the HAWC Gamma-Ray Observatory

The High Altitude Water Cherenkov (HAWC) gamma-ray observatoryis a wide fieldof view observatorysensitive to 500 GeV - 100 TeV gamma raysand cosmic rays. It can also perform diverse indirectsearches for dark matter(DM) annihilationand decay. Among the most promising targets for the indirectdetection of dark matterare dwarf spheroidal galaxies. These objects are expected to have few astrophysical sources of gamma raysbut high dark mattercontent, making them ideal candidates for an indirect dark matterdetection with gamma rays. Here we present individual limits on the annihilationcross section and decay lifetime for 15 dwarf spheroidal galaxieswithin the HAWC field-of- view, as well as their combined limit. These are the first limits on the annihilationcross section and decay lifetime using data collected with HAWC.
