51. BSM Physics with Light Particles

Prof. Mikhail Shaposhnikov (EPFL)

2/4/21, 5:00 PM

I will discuss the motivations for physics beyond the Standard Model below the Fermi scale, resulting in the existence of feebly interacting long-lived particles. The experimental prospects to search for these particles will be outlined.

52. Fixed target experiments using electron and positron beams

Yasuhito Sakaki (KEK)

2/10/21, 10:00 AM

Now that new heavy particles have not been found at the LHC, focusing on light and weakly interacting new particles is one direction to go. Fixed target experiments using accelerators play a part in this. I will explain the basics of the phenomena in fixed target experiments, and how to calculate the number of signal on a target induced by e+ e- beams. Trends in some fixed-target experiments...
