Tree-level UV completions for N_RSMEFT d=6 and d=7 operators
read the original abstract
We study ultra-violet completions for operators in standard model effective field theory extended with right-handed neutrinos ($N_R$SMEFT). Using a diagrammatic method, we generate systematically lists of possible tree-level completions involving scalars, fermions or vectors for all operators at $d=6$ and $d=7$, which contain at least one right-handed neutrino. We compare our lists of possible UV models to the ones found for pure SMEFT. We also discuss how the observation of LNV processes via $N_R$SMEFT operators at the LHC can be related to Majorana neutrino masses of the standard model neutrinos.

Direct constraints on the agnostic $\nu$SMEFT from heavy-neutrino searches at the LHC
A recast of CMS same-sign-dimuon data places the first direct bounds on the agnostic νSMEFT, excluding couplings below ~5.8×10⁻⁷ GeV⁻² at m_N≈1.5 TeV.

Challenging Majorana neutrino effects in $B\to K^{(\ast)}\nu\nu$ and $K\to \pi\nu\nu$ decays
Belle-II's B→Kνν excess cannot be explained by dimension-7 lepton-number-violating SMEFT operators without fine-tuning neutrino masses, while a light sterile-neutrino extension can, with testable decay spectra.
