Status of neutron magnetic moment?

Click For Summary

Discussion Overview

The discussion revolves around the status of the neutron magnetic moment and its relation to standard model calculations. Participants explore recent measurements and their implications, as well as potential connections to other particles like the muon.

Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • One participant recalls recent comments about the neutron magnetic moment measurements being in disagreement with standard model predictions, though specifics are unclear.
  • Another participant suggests that neutrons might exhibit increased magnetism at certain temperatures, although this is not directly related to the original query.
  • A participant clarifies that the discussion is more about the standard model and mentions a measurement being close to the standard model limits, hinting at potential new physics.
  • A later reply corrects the focus to the muon anomalous moment, which is noted to be slightly beyond standard model calculations, rather than the neutron magnetic moment.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as there are competing views regarding the focus on the neutron versus the muon, and the specifics of the measurements remain unclear.

Contextual Notes

Details about the specific measurements and their implications are missing, and there is uncertainty regarding the exact nature of the discrepancies with standard model predictions.

I believe to remember some recent comments about the measurement of neutron magnetic moment or some other quantity of this particle, which was not very well in agreement with standard model calculations. I can not remember which measurement it was, or when. Can anyone help my poor neurons?
 
Physics news on Phys.org
Neutrons could perhaps become highly magnetic at ceirtain temperatures. Why don't you post this at physics help?
 
Er... it was Standard Model related, more than "physics help". I believe to remember that it was a measure just in the border (2-3 deviations or so) of standard model, thus sort of hint of new physics and blah blah.

Sorry it seems I have already used the 100% of my brain :-) and I can not remember more details.
 
Hmm my memory returned. It is the muon anomalous moment which is now slightly beyond the standard model calculation. No the neutron :-(
