Photoproduction of $WH$ signal at electron-proton Colliders
  We present the photoproduction of an intermediate mass Higgs (IMH) boson associated with a $W$ boson at the future electron-proton colliders using bremsstrahlung photon beam or laser backscattered photon beam. With bremsstrahlung photon beam the search for the IMH boson is unfavorable because of the small signal rate. But with laser photon beam the search is viable due to a much larger rate, and provided that the $B$-identification is efficient and $m(b\bar b)$ measurement has a good resolution.
