5-6pm, October 31, 2017 is the International Dark Matter day!

To celebrate this, I will give a short talk about "MiniBooNE-DM", the direct production and direct detection dark matter experiment at Fermilab.

According to vector portal models, sub-GeV dark matter particles can be generated at the beam dump of the Booster Neutrino Beamline at Fermilab, USA, and detected with the kilo-ton scale MiniBooNE neutrino detector. MiniBooNE-DM is looking for signatures of such accelerator-produced high energy dark matter that scatter off nucleons, producing scintillation light which can be detected by photo-multiplier tubes. The accurate timing of events from the accelerator beam structure will provide additional information to detect dark matter through its sub-luminal time-of-flight.

In this short talk, I will describe the basics of dark matter, Booster neutrino beamline and the MiniBooNE detector, and the first result of search of dark matter particles (https://arxiv.org/abs/1702.02688).
