    "abstract": "We calculate contributions of hadron resonances to two-photon exchange\neffects in electron-proton scattering. In addition to the nucleon and P33\nresonance, the following heavier resonances are included as intermediate states\nin the two-photon exchange diagrams: D13, D33, P11, S11 and S31. We show that\nthe corrections due to the heavier resonances are smaller that the dominant\nnucleon and P33 contributions. We also find that there is a partial\ncancellation between the contributions from the spin 1/2 and spin 3/2\nresonances, which results in a further suppression of their aggregate\ntwo-photon exchange effect.",
