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 »
Nov. 21, 2019, 5:00 pm US/Central	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...

Dec. 5, 2019, 4:30 pm US/Central	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...

Consequencies are that world-line time (as in Feynman diagrams) is a closed loop with no beginning or end, different from thermodynamic or psychological time which is transient, not relevant at the Big...
