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, the speaker 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.
