Pair production of the T-odd leptons at the LHC

Abstract

The T-odd leptons predicted by the littlest $Higgs$ model with T-parity can be pair produced via the subprocesses $gg\to {\ell }_H^{+}{\ell }_H^{-}$, $q\bar{q}\to {\ell }_H^{+}{\ell }_H^{-}$, $\gamma \gamma \to {\ell }_H^{+}{\ell }_H^{-}$ and $VV\to {\ell }_H^{+}{\ell }_H^{-}$ ($V$=$W$ or $Z$) at the $CERN$ Large Hadron Collider $(LHC)$. We estimate the hadronic production cross sections for all of these processes and give a simply 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 $q\bar{q}\to {\ell }_H^{+}{\ell }_H^{-}$ can reach $270fb$.
