These muons are becoming the fashionable particles of the moment.
I mentioned at the beginning of this year (2017) of the use of muon tomography to image the damaged core at Fukushima. Now, muons are making headlines in two separate applications.
The first is the use of cosmic muons imaging that discovered hidden chambers inside Khufu's Pyramid at Giza. The second is more use of muons to probe the status of nuclear waste safely.
The comment I wrote in the first link still stands. We needed to know the fundamental properties of muons FIRST before we could actually use then to all these applications. And that fundamental knowledge came from high-energy/elementary particle physics.
So chalk this up to another application of such an esoteric field of study.
