QCD compositeness as revealed in exclusive vector boson reactions through double-photon annihilation: e+e−→γγ⁎→γV0 and e+e−→γ⁎γ⁎→V0V0

QCD compositeness as revealed in exclusive vector boson reactions through double-photon annihilation: e+e−→γγ⁎→γV0 and e+e−→γ⁎γ⁎→V0V0

We study the exclusive double-photon annihilation processes, e+e−→γγ⁎→γV0 and e+e−→γ⁎γ⁎→Va0Vb0, where the Vi0 is a neutral vector meson produced in the forward kinematical region: s≫−t and −t≫ΛQCD2. We show how the differential cross sections dσdt, as predicted by QCD, have additional falloff in the...
