Seminar

Title: Dark matter direct detections and the neutrino floor

Speaker: Prof. Wei Chao (晁伟)(BNU)

Time: 10:00 AM, Oct. 10th (Thursday), 2019

Place: R319, Theoretical Physics Division

Abstract: Cosmological observations tell us that about 26.8% of the energy present in the universe should be dark matter (DM), which behaviors just like a beyond standard model particle and interacts weakly with the ordinary matter. In this talk, I will discuss issues relevant for the direct detections of cold DM in underground laboratories, with special emphasis on the neutrino floor, which is the background induced by coherent elastic neutrino-nucleus scattering. Impacts of new physics to the neutrino floor as well as the DM-nucleus scattering will be discussed.
