The SENSEI team at Fermilab is designing and planning to fly a HAB mission(s) that carries a SkipperCCD to the edge of space in order to search for strongly interacting sub-GeV dark matter above 99.9% of Earth’s atmosphere. NASA’s Jet Propulsion... More »

20191114 Nov. 14, 2019, 4:30 pm Colliding light to make dark matter and measure tau g–2 Jesse Liu, U Chicago Dark matter is mysterious because it doesn’t interact with light. How remarkable it would be if we made it in the lab by colliding light. Using the LHC as the highest energy broadband photon collider ever built opens dark matter searches using the missing momentum 4-vector via proton tagging. I then propose using heavy ion... More »
20191121 Nov. 21, 2019, 5:00 pm Dark sector searches using nonlinear optics Mattias Senger In my talk I will explore a way to combine nonlinear optics with dark sector searches, and talk about a “toy experiment” we have running at SiDet. Improvements on this experimental technique might give new insights on dark sector. The technique is inspired in a nonlinear optics process known as “spontaneous parametric down conversion” in...

20191205 Dec. 5, 2019, 4:30 pm Baryogenesis, Neutron Oscillations, and Looking Toward Future Experiments Josh Barrow, UTK Just one of Sakharov’s conditions of baryogenesis has not yet been observed experimentally: baryon number violation. Finding such a rare signal would be an experimental triumph. I’ll review some of the essence of baryogenesis, B-L conservation in the Standard Model, the sphaleron, the possibility of B-L violation, why low scale baryogenesis should be investigated, and...
