Stern-Gerlach experiment with Gravitons

Click For Summary
SUMMARY

The discussion centers on the application of the Stern-Gerlach experiment to gravitons, which are theorized to possess spin 2. Despite advancements in generating strong magnetic fields, no evidence of diffracted gravitons has been observed. The participants speculate that this absence may be due to gravitons being virtual particles, which raises questions about their interaction with magnetic fields. The relationship between magnetic moment and spin is highlighted, particularly the equation μ = g q/2m S, emphasizing the significance of the g-factor in this context.

It has long been predicted that gravitons will be spin 2. If that is true, then if we have a sufficient magnetic field, what is to stop us from recreating the Stern-Gerlach experiment and using a magnetic field to diffract them?

Now, we have made very strong magnetic fields and to my knowledge, diffracting gravitons have never been detected.

The only reason I can think of, is that the gravitons are virtual, but that should not mean the magnetic field does not effect them, right?

The B-field does not couple to the spin but to the magnetic moment μ which is proportional to the spin S

μ = g q/2m S

where the dimensionless quantity g is called the g-factor.

For a elementary, massless, uncharged particle it is natural to assume g=0 (there may be quantum effects changing this relation).

Before asking this question regarding gravitons one should try to answer this question for photons.
