6. Dark Matter

Mini-symposium on Dark Matter: from WIMP to axions/ALP, from laboratory search to astrophysical constraints


Dark matter is an hypothetical form of matter that makes up a large fraction of the mass in the Universe. The existence of dark matter is inferred through its gravitational interactions with ordinary “baryonic” matter and light, and it is essential in driving gas and dust to build up into stars and galaxies.

The search for this elusive component of the cosmo is currently being tackled from the theory side through advanced modeling and statistical analyses, as well as from the experimental side where current and near-future installments will be covering large portions of the model space. Among the experimental techniques are direct detection (PandaX), indirect detection (DAMPE) and laboratory production (DarkSHINE).

This mini-symposium aims at covering the recent developments for some of the best motivated dark matter models, along with reporting on the progresses and future reaches of the experimental communities. The following topics will be covered:

1. Light dark matter (axions, dark photons, fuzzy dark matter).

2. Weakly Interacting Massive Particles.

3. Primordial Black Holes as Dark Matter.

Deadlines for abstract submission and registration are the same as for the general symposium, and can be found at the conference website:
