Signals of the littlest Higgs model with T-parity at $eγ$ and $ep$ collisions

Abstract

Littlest Higgs model with T-parity predicts the existence of the neutral, weakly interacting, new gauge boson $B_{H}$, which can be seen as an attractive dark matter candidate. We study production of the new gauge boson $B_{H}$ via $eγ$ and $ep$ collisions. We find that $B_{H}$ can be abundantly produced via the subprocesses $e^{-}γ\to L^{-}B_{H}$ and $γq\to B_{H}Q$, which might give rise to characteristic signals. Some discussions about the $SM$ backgrounds for this kind of signals are also given.
