The thermal decoupling description of multi-TeV scale dark matter (DM) and co-annihilating partners is reconsidered. In such a high-mass region, even the electroweak force carriers could act as long-range forces, leading to the existence of meta-stable DM bound states. The formation and subsequent decay of the latter further depletes the relic density on top of the Sommerfeld enhancement,...
PandaX is a dark matter search experiment located at China Jin Ping Underground Lab using xenon time projection chamber.
In this talk, I will present the latest result from PandaX-II experiment and the current status of PandaX-4T experiment.
We present nearly self-consistent stellar-halo models of the dwarf spheroidal Fornax galaxy the satellite of the Milky Way galaxy. Such galaxies are dark matter dominated objects with almost no gas in them so they are excellent objects for N-body modelling that takes into account visible and dark matter(DM) halo components. Three models are self-consistent realizations containing a truncated...
In the MeV gamma-ray band, the observed Galactic diffuse gamma-rays has the excessive component cannot be explained by the current standard model of the Galaxy. This excess might be gamma-rays due to annihilation of MeV scale WIMP dark matter or evaporations of primordial black holes. The MeV band has the advantage over the GeV band because there is less diffuse gamma-ray background due to no...
WIMP DMs in the Universe accumulate in neutron stars (NSs) through their interactions with nucleons. It has been known that their annihilation inside the NS core causes late-time heating, with which the surface temperature becomes $T_s \simeq (2-3) \times 10^3$ K for the NS age $t > 10^{6-7}$ years. Thus the measurement of NS surface temperature can be used as a new probe of WIMP DMs. Because...
The next generation of gamma-ray experiments are expected to improve significantly the current results in the search for Dark Matter (DM). Before these next-generation instruments start operating at their nominal design, one possibility to improve the current results is to combine data from existing experiments. This technique allows to increase energy coverage by combining data from...
In this talk, we will present a status report on the search for dark matter spectral lines around the Galactic centre (GC) with the MAGIC telescope system located on the Canary island of La Palma, Spain. MAGIC is sensitive to gamma rays from 50 GeV to 50 TeV. So far, MAGIC has produced groundbreaking results in the field of indirect DM searches observing a variety of targets, such as the...
It is possible that DM particles are secluded to their own dark sector, where the interactions are carried by one or several dark mediators. If this dark sector exists, DM particles do not couple directly to the standard model (SM) particles, as in the case of WIMP scenarios. However, indirect DM searches are still possible if we assume that dark mediators are coupled to SM particles through a...
