Description

Particle physics is at crossroads: the Standard Model is confirmed with unprecedented precision after decades of experimental explorations, and yet it offers no explanation to some of the most profound scientific puzzles such as the nature of dark matter and dark energy. Moreover, past theoretical guiding principles such as naturalness have not bore fruit in experimental searches. Quo vadis particle physics?

Pondering on the future, we would like to gather a small group of theoretical and experimental experts in an informal setting to evaluate the current state of affairs and devise future strategies, all surrounded by the natural beauty of Hokkaido in the winter.

In this inaugural workshop, we plan to devote a significant amount of effort to the muon as a common thread between a very high energy collider and other low energy precision tests of the Standard Model, as well as their possible synergies. Complementary probes via dark sectors, neutrinos and axions, as well as quantum measurements and quantum sensing, will also be covered.

 

Organizers:
Shusei Kamioka (KEK)
