T奇轻子在LHC上的对产生

Pair production of the T-odd leptons at the LHC

Chong-Xing Yue, Yong-Zhi Wang, Wei Lui, Wei Ma

摘要:

T宇称最小$Higgs$模型预言的T奇轻子可以在$CERN$大型强子对撞机$(LHC)$上通过子过程$gg\to \ell^{+}_{H}\ell^{-}_{H}$、$q\bar{q}\to \ell^{+}_{H}\ell^{-}_{H}$、$γγ\to \ell^{+}_{H}\ell^{-}_{H}$和$ VV \to \ell^{+}_{H}\ell^{-}_{H}$($V$ = $W$或$Z$)成对产生。我们估计了这些过程的强子产生截面,并作了简单的唯象分析。我们发现,上述过程中的大多数的横截面是非常小的。然而,$Drell-Yan$过程$q\bar{q}\to \ell^{+}_{H}\ell^{-}_{H}$的横截面值可达到$270fb$。

英文摘要:

The T-odd leptons predicted by the littlest $Higgs$ model with T-parity can be pair produced via the subprocesses $gg\to \ell^{+}_{H}\ell^{-}_{H}$, $q\bar{q}\to \ell^{+}_{H}\ell^{-}_{H}$, $γγ\to \ell^{+}_{H}\ell^{-}_{H}$ 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 $270fb$.
