Abstract
The resonances (ηc,χc0,c2) contribution to two-photon exchange (TPE) effects in is calculated in a simple hadronic model. The calculation shows the TPE contributions by resonance χc2, which are dependent on the unknown phases ϕE,M of protonʼs time-like form factors GE,M, are much larger than the TPE contributions by non-resonance and are comparable with measurement precision of coming PANDA detector at for most ϕE,M.
