Potential for measurement of the tensor magnetic polarizability of the deuteron in storage ring experiments

TL;DR

This paper derives formulas for deuteron spin dynamics in storage rings, showing how tensor magnetic polarizability can be measured through induced polarization effects, and confirms previous theoretical predictions about spin rotation phenomena.

Contribution

It introduces new formulas for deuteron spin behavior considering tensor polarizabilities and proposes a method to measure the tensor magnetic polarizability in storage ring experiments.

Findings

Deuteron beam can acquire ~1% horizontal polarization due to tensor polarizability.

Tensor magnetic polarizability causes spin rotation with two frequencies and beating effects.

Theoretical confirmation of previously predicted spin rotation phenomena.

Abstract

General formulas describing deuteron spin dynamics in storage rings with allowance for the tensor electric and magnetic polarizabilities are derived. It is found that an initially tensor-polarized deuteron beam can acquire a final horizontal vector polarization of the order of 1%. This effect allows one to measure the tensor magnetic polarizability of the deuteron in storage ring experiments. We also confirm an existence of the effect found by Baryshevsky and Gurinovich, hep-ph/0506135 and Baryshevsky, hep-ph/0510158; hep-ph/0603191 that the tensor magnetic polarizability of the deuteron causes the spin rotation with two frequencies and experiences beating for polarized deuteron beams in storage rings.
