Comment on "Nuclear structure corrections in muonic deuterium"

TL;DR

This paper discusses the effects of deuteron polarizability and the third Zemach moment in muonic deuterium, confirming their cancellation and highlighting implications for the proton radius puzzle.

Contribution

It clarifies and emphasizes the cancellation between deuteron polarizability effects and the third Zemach moment in muonic deuterium, building on prior findings.

Findings

Third Zemach moment effects are canceled by deuteron polarizability effects.

Confirmation of previous results on deuteron polarizability impacts.

Highlights importance for understanding the proton radius puzzle.

Abstract

A recent letter [1] investigated the effects of deuteron polarizability in the mu D atom. The importance of understanding this atom has been heightened because of the possible light it could shed on the proton radius puzzle. Here we confirm, clarify, and emphasize the significance of the result [1] that the effects of the third Zemach moment are canceled by part of the deuteron polarizability effects. 1. K.
