The High Altitude Water Cherenkov (HAWC) Gamma-ray Observatory, located in the mountains
of Mexico, has been performing an unbiased survey of the Northern sky at energies above 300 GeV
since becoming fully operational in 2015. HAWC’s wide field-of-view enables indirect searches
for TeV-scale dark matter from diverse targets including galaxy clusters, dwarf spheroidal galaxies,
the Milky Way galactic halo and the Sun. Beyond dark matter, sensitivity to transient bursts of
gamma-rays provides a window into the early universe through searches for evaporating primordial
black holes and its high energy reach enables searches for violations of the Lorentz symmetry. I
will present an overview of beyond-the-Standard-Model searches with HAWC and present some
of the world’s strongest constraints on these processes at the TeV scale.
