Abstract

We investigate a two Higgs doublet model with extra flavour depending U(1)XU(1)_X gauge symmetry where ZZ' boson interactions can explain the Atomki anomaly by choosing appropriate charge assignment for the SM fermions. For parameter region explaining the Atomki anomaly we obtain light scalar boson with O(10)\mathcal{O}(10) GeV mass, and we explore scalar sector to search for allowed parameter space. We then discuss anomalous magnetic dipole moment of muon and lepton flavour violating processes induced by Yukawa couplings of our model.
