Claims

C1strongest claim

From the observed tilts, we derive the first experimental limit on the deuteron EDM, |d^d|< 2.5·10^{-17} e·cm (95% C.L.).

C2weakest assumption

The assumption that the few-milliradian spin-axis tilts, stated to be dominated by systematic effects, can be accurately modeled and bounded so that the residual provides a reliable upper limit on any EDM contribution without the systematics either masking a signal or being misattributed.

C3one line summary

First experimental limit on deuteron EDM: |d^d| < 2.5 × 10^{-17} e·cm (95% CL) from observed spin-axis tilts in a magnetic storage ring.
