Abstract

The T-odd leptons predicted by the littlest Higgs model with T-parity can be pair produced via the subprocesses $gg\rightarrow \ell ^{+}_{H}\ell ^{- }_{H}$ , $q\overline{q}\rightarrow \ell^{+}_{H}\ell^{-}_{H}$ , $\gamma \gamma \rightarrow \ell ^{+}_{H}\ell ^{- }_{H}$ , and $VV\rightarrow \ell ^{+}_{H}\ell ^{- }_{H}$ ( $V = W$ or Z) at the CERN large hadron collider (LHC). We estimate the hadronic production cross-sections for all of these processes and give a simple phenomenology analysis. We find that the cross-sections for most of the above processes are very small. However, the value of the cross-section for the Drell-Yan process, $q\overline{q}\rightarrow \ell^{+}_{H}\ell^{-}_{H}$ , can reach 270 fb.
