- We consider the electromagnetic form factors ratio in the Rosenbluth and polarization methods. We explore the impact of adding new particles as the mediators in the electron-proton scattering on these ratios. Consequently, we find some bound on the scalar coupling as $α_{sc}\sim 10^{-5}$ for $m_{sc}\sim 5 MeV-2 GeV$ and $α_{sc}\sim 10^{-4}-10^{-3}$ for $m_{sc}\sim 2-10 GeV$. Meanwhile, the vector coupling is bounded as $α_v\sim 10^{-5}$ for $m_v\sim 5 MeV-1.1 GeV$ and $α_v\sim 10^{-4}-10^{-3}$ for $m_v\sim 1.2-10 GeV$. These constraints are in complete agreement with those which is found from other independent experiments.
