New spin structure constraints on hyperfine splitting and proton Zemach radius

New spin structure constraints on hyperfine splitting and proton Zemach radius

The 1S hyperfine splitting in hydrogen is measured to an impressive ppt precision and will soon be measured to ppm precision in muonic hydrogen. The latter measurement will rely on theoretical predictions, which are limited by knowledge of the proton polarizability effect Δpol. Data-driven evaluatio...
