Title: Two-photon exchange correction to the hyperfine splitting in muonic hydrogen,
Abstract: We reevaluate the Zemach, recoil and polarizability corrections to the
hyperfine splitting in muonic hydrogen expressing them through the low-energy
proton structure constants and obtain the precise values of the Zemach radius
and two-photon exchange (TPE) contribution. The uncertainty of TPE correction
to S energy levels in muonic hydrogen of 105 ppm exceeds the ppm accuracy level
of the forthcoming 1S hyperfine splitting measurements at PSI, J-PARC and
RIKEN-RAL.
