英文摘要: In this work, the two-photon-exchange (TPE) effects in the unpolarized mu p scattering are discussed within the hadronic model where the intermediate states N, Delta, and sigma are considered. The contribution from the N intermediate is close to the results given by Tomalak and Vanderhaeghen [Phys. Rev. D 90, 013006 (2014)] at small Q, and there is a sizable difference when Q > 0.25 GeV (where Q(2) is the four-momentum transfer). The contributions from the Delta and the s intermediate states are much smaller than that from the N intermediate at small Q. In the kinematic region with k(i) subset of [0.01,0.3] GeV and Q <= 0.4 GeV (where k(i) is the three-momentum of initial muon in the laboratory frame), a naive expression for the TPE contributions is given, which can be used directly for other analysis.
