| Summary:
Real scalar triplet dark matter, which is known to be an attractive candidate
for a thermal WIMP, is comprehensively studied paying particular attention to
the Sommerfeld effect on the dark matter annihilation caused by the weak
interaction and the other interaction between the dark matter and the Higgs
boson. We find a parameter region that includes the so-called ‘WIMP-Miracle’
one is still surviving, i.e. it respects all constraints imposed by dark matter
searches at collider experiments, underground experiments (direct detection)
and astrophysical observations (indirect detection). The region is also found
to be efficiently searched for by various near future experiments. In
particular, the XENONnT experiment will cover almost the entire parameter
region.
