What consequences does a positive muon anomalous magnetic moment have for astronomy? On April 7th, 2021, the muon $(g-2)$ collaboration published Measurement of the Positive Muon Anomalous Magnetic Moment to 0.46 ppm, a result which made it to standard news, partly under headlines like Farewell to the Standard Model (German source: Abschied vom Standardmodell)
The following quote from phys.org nicely summarizes what it is in general about:

The experiment at Brookhaven indicated that g-2 differed from the theoretical prediction by a few parts per million. This miniscule difference hinted at the existence of unknown interactions between the muon and the magnetic field—interactions that could involve new particles or forces.

I am now wondering if there are theoretical studies which illuminate what concrete effects a $g-2 &gt; 0$ would have on astronomy, as e.g. Dominik Stöckinger states (translation by me):

Some variants of supersymmetry, in which so-called superpartner particles also explain dark matter, are no longer tenable by this measurement.

An answer to What is the closest candidate for Dark Matter currently? points out that WIMPS are currently the most appealing candidate for dark matter.
This is unlikely to have any implications for astronomy. They may have seen an extremely small deviation from the predictions of the standard model. The result may actually have to do with technical issues in theoretical methods, not with any new physics: https://arxiv.org/abs/2002.12347 . Even if it does have implications for new physics, there is no reason to believe that it would have implications for astronomy. It could, for example, be an indication of the existence of a new unstable particle with a high mass, whereas dark matter needs to be made of stable particles.
