update on Kramers-Kronig relation for proton — •Oleksii Gryniuk1,2, Franziska Hagelstein1, and Vladimir Pascalutsa1 — 1JGU, Mainz, Germany — 2KNU, Kyiv, Ukraine
New evaluation of the Baldin sum rule and forward Compton scattering amplitude, as well as higher order sum rules, was made with updated data for proton total photoabsorption cross-section. Stability of resulting values, comparison to previous evaluations and consequences of results for higher order sum rules are discussed.
