On today's news, it says that Fermilab have done measurements on the spin of muons and that they are measured to wobble faster than expected according to current physics theories.
Apparently this may turn physics 'on it's head' and suggests that there might be a fifth force.
What measurements have been made?
and
Why do the measurements suggest the need for a fifth force?
Here is an extract from the BBC article
https://www.bbc.co.uk/news/56643677
"The Muon g-2 experiment involves sending the particles around a 14-metre ring and then applying a magnetic field. Under the current laws of physics, encoded in a theory known as the Standard Model, this should make the muons wobble at a certain rate. Instead, the scientists found that muons wobbled at a faster rate than expected. They say this might be caused by a force of nature that's completely new to science. Fermilab is America's premier particle physics lab.
No one yet knows what this potential new force does, other than influence muon particles. Theoretical physicists believe that it might also be associated with an as-yet undiscovered sub-atomic particle. There is more than one concept for what this hypothetical particle might be. One is called a leptoquark, another is the Z' boson (Z-prime boson)."
Does anyone know any more details?
