Abstract
- The dark photon is a new gauge boson which arises from an extra $$U'(1)$$ U ′ ( 1 ) gauge symmetry. In this paper, a novel dark photon production mechanism based on MeV-scale $$\gamma $$ γ – $$\gamma $$ γ collider is considered: $$\gamma \gamma \rightarrow \gamma A'$$ γ γ → γ A ′ . With the aid of PACKAGE-X, differential cross section of $$\gamma \gamma \rightarrow \gamma A'$$ γ γ → γ A ′ is obtained, as a function of the kinetic mixing parameter $$\varepsilon $$ ε and dark photon mass $$m_{A'}$$ m A ′ . Taking the light-by-light scattering as background, the constraints on the dark photon parameter space for different time intervals in a MeV-scale $$\gamma $$ γ – $$\gamma $$ γ collider are also given.
