Probing the Weinberg Operator at Colliders

Motivated by searches for 0νββ decay in nuclear experiments and collider probes of lepton number violation at dimension d≥7, we investigate the sensitivity to the d=5 Weinberg operator using the nonresonant signature pp→ℓ±ℓ′±jj at the LHC. We develop a prescription for the operator that is applicabl...

description Motivated by searches for 0νββ decay in nuclear experiments and collider probes of lepton number violation at dimension d≥7, we investigate the sensitivity to the d=5 Weinberg operator using the nonresonant signature pp→ℓ±ℓ′±jj at the LHC. We develop a prescription for the operator that is applicable in collisions and decays, and focus on the ℓℓ′=μμ channel, which is beyond the reach of nuclear decays. For a Wilson coefficient C5μμ=1, scales as heavy as Λ∼8.3(11)  TeV can be probed with L=300  fb-1(3  ab-1). This translates to an effective μμ Majorana mass of |mμμ|∼7.3(5.4)  GeV and establishes a road map for testing the Weinberg operator at accelerators.

We develop a prescription for the operator that is applicable in collisions and decays, and focus on the $\ell\ell'=\mu\mu$ channel, which is beyond the reach of nuclear decays. For a Wilson coefficient $C^{\mu\mu}_5=1$, scales as heavy as $\Lambda\sim 8.3~(11)$~TeV can be probed with $\mathcal{L}=300~{\rm fb}^{-1}~(3~{\rm ab}^{-1})$. This translates to an effective $\mu\mu$ Majorana mass of $\vert m_{\mu\mu}\vert\sim7.3~(5.4)$~GeV, and establishes a road map for testing the Weinberg operator at accelerators.arXiv:2012.09882CP3-20-63DESY-20-230DESY 20-230IFJPAN-IV-2021-3MCNet-20-23oai:cds.cern.ch:27488122020-12-17
