Event Description 

I will discuss two ideas of probing the nature of dark matter candidates from the so-called dark sector models where new forces exist and act only on dark matter. Both are related to bound state physics of dark matter and its antiparticle. First, I will discuss producing such bound states at colliders, the unusual signatures, and a constraint derived based on BaBar data. In the second part, I consider cosmologically long-lived dark matter bound states that may exist in nature. When striking on a target they undergo "self-destruction" and deposit all the energy into visible particles. Neutrino detectors are the best places to search for this new phenomenon.
