Scientists at Fermilab close in on fifth force of nature
Scientists at Fermilab close in on fifth force of nature
Physicists believe that an unknown force could be acting on sub-atomic particles known as muons.
Its "heart", right?
For a mainstream press article about science, it's pretty good. I do wish they had touched on the failure of recent experiment to verify some of the theoretical particles predicted by the standard model.
This is another reminder that the anomalous magnetic moment of the muon was recalculated by two different groups using higher precision lattice QCD techniques and wasn't found to be significantly different from the Brookhaven/Fermilab "discrepancy". More work needs to be done to check for errors in the original and newer calculations, but it seems quite likely to me that this will ultimately confirm the standard model exactly as we know it and not provide any new insight or the existence of another force particle.
My hunch is that unknown particles like dark matter rely on a relatively simple extension of the standard model (e.g. supersymmetry, axioms, etc.) and the new physics out there that combines gravity and QM is something completely different from what we are currently working on and can't be observed with current colliders or any other experiments on Earth.
So probably we will continue finding nothing interesting for quite some time until we can get a large ML model crunching every single possible model to check for fit on the data, and hopefully derive some better insight from there.
Though I'm not an expert and I'm talking out of my ass so take this all with a grain of salt.

Since then, the research team has gathered more data and reduced the uncertainty of their measurements by a factor of two, according to Dr Brendan Casey, a senior scientist at Fermilab.
In an experiment with the catchy name 'g minus two (g-2)' the researchers accelerate the sub-atomic particles called muons around a 15m-diameter ring, where they are circulated about 1,000 times at nearly the speed of light.
The researchers found that they might be behaving in a way that can't be explained by the current theory, which is called the Standard Model, because of the influence of a new force of nature.
Dr Mitesh Patel from Imperial College London is among the thousands of physicists at the LHC attempting to find flaws in the Standard Model.
Prof Graziano Venanzoni, of Liverpool University, who is one of the leading researchers on the project, told BBC News that this might be caused by an unknown new force.
Researchers know that there is what they describe as "physics beyond the Standard Model" out there, because the current theory can't explain lots of things that astronomers observe in space.
I feel bad for the fith force. It's probably just scared.
Stop closing in on me!
Run faster, the scientists are gaining ground!!
Sounds dope. I wonder if it will bring more clarity or more puzzles. My bet is on the latter. Which is great.
