"General Relativity experiment with spin polarized particle beams"


címmel tartandó szemináriumára.

Kivonat:

In experimental proposals published in the last two decades, a so called frozen spin storage ring concept emerged as a method for setting upper experimental bounds to electric dipole moment (EDM) of elementary particles. In a recent paper of ours, a fully covariant general relativistic (GR) calculation was presented concerning the Earth's gravitational modification effect on the spin transport, in such mixed magnetic-electric frozen spin storage rings. That GR effect contributes to such EDM measurement. It was shown that under the frozen spin condition, similarly to an EDM signal, GR causes a sizable spin precession out of the orbital plane. We propose to use this finding to perform an experimental test of GR in a very interesting regime: using microscopic particles, at relativistic speeds, moving along non-geodesic (accelerating) trajectories, and the tensorial nature of GR would be at test, not merely the gravitational drag. Our main finding is that one needs to use large magnetic anomaly particle beams, such as tritons, or helion3, or protons, in order to make such an experiment feasible. The experiment is not economic with small magnetic moment particles such as deuteron, muon or electron beams.
