摘要:

在这项工作中,我们调查的可能性探测一类中微子质量模型在LHC质子-质子碰撞与8和14 TeV的能量。与轻子耦合的单重态标量$S^{\pm}$的轻子味破坏相互作用的存在可以诱导出许多过程,如$pp\rightarrow\ell_α^{\pm}\ell_β^{\mp}+\slashed E $。使用过程与$\ell_α\ell_β=ee,eμ,μμ$,我们发现,一个包含削减的$M_{T2}$事件变量是至关重要的,在我们的分析,并导致一个有效的抑制大标准模型的背景。我们的研究结果表明带电标量效应可能是可检测的,特别是在$\sqrt{s}= 14~\text{TeV}$。

英文摘要:

In this work, we investigate the possibility of probing a class of neutrino mass models at the LHC proton-proton collisions with 8 and 14 TeV energies. The existence of lepton flavor violating interactions for a singlet charged scalar, $S^{\pm}$, that couples to the leptons could induce many processes such as $pp\rightarrow\ell_α^{\pm}\ell_β^{\mp}+\slashed E $. Using the processes with $\ell_α\ell_β=ee,eμ,μμ$, we found that an inclusive cut on the $M_{T2}$ event variable is vital in our analysis and leads to an effective suppression of the large Standard Model background. Our results show possible detectability of the charged scalars effect, especially at the $\sqrt{s}= 14~\text{TeV}$.
