论文摘要
通过搜索$0νβ$衰减的核试验和对撞机探针的动机，在维度$ d \ geq7 $处违反了违规的撞机探针，我们研究了对$ d = 5 $ weinberg操作员的敏感性，使用非呼吸签名$ pp \ to \ ell^el^el^\ ell^\ ell^\ ell'^{我们为操作员开发了适用于碰撞和衰减的操作员处方，并专注于$ \ ell \ ell'=μ$通道，这是核衰减的范围。对于Wilson系数$ C^{μμ} _5 = 1 $，可以用$ \ Mathcal {l} = 300〜 {\ rm fb}^{ - 1}^{ - 1}〜（3〜 {\ rm ab ab}^^$ 1} $ 1} $ c \ sim \ sim 8.3〜（11）$ 〜TEV探测$ 〜TEV。这将转化为有效的$μ$ majora质量，为$ \ vert m_ {μμ} \ vert \ sim7.3〜（5.4）$ 〜GEV，并建立了在加速器上测试温伯格操作员的路线图。
Motivated by searches for $0νββ$ decay in nuclear experiments and collider probes of lepton number violation at dimension $d\geq7$, we investigate the sensitivity to the $d=5$ Weinberg operator using the non-resonant signature $pp\to \ell^\pm \ell'^{\pm} j j$ at the LHC. We develop a prescription for the operator that is applicable in collisions and decays, and focus on the $\ell\ell'=μμ$ channel, which is beyond the reach of nuclear decays. For a Wilson coefficient $C^{μμ}_5=1$, scales as heavy as $Λ\sim 8.3~(11)$~TeV can be probed with $\mathcal{L}=300~{\rm fb}^{-1}~(3~{\rm ab}^{-1})$. This translates to an effective $μμ$ Majorana mass of $\vert m_{μμ}\vert\sim7.3~(5.4)$~GeV, and establishes a road map for testing the Weinberg operator at accelerators.
