abstract = {We study the phenomenology of the simplest renormalisable model that, at low
energy, leads to the effective  eld theory of the Standard Model extended with right-handed
neutrinos (SMEFT). Our aim is twofold. First, to contextualise new collider signatures
in models with sterile neutrinos so far studied only using the bottom-up approach. And
second and more important, to provide a thorough example of one-loop matching in the diagrammatic approach, of which other matching techniques and automatic tools can bene t
for cross-checks. As byproducts of this work, we provide for the  rst time: (i) a complete
off-shell basis for the vSMEFT and explicit relations between operators linked by equations
of motion; (ii) a complete basis for the low-energy e ective  eld theory (vLEFT) and the
tree-level matching onto the vSMEFT; (iii) partial one-loop anomalous dimensions in the
vLEFT. This way, our work comprises a new step forward towards the systematisation of
one-loop computations in effective  eld theories, especially if the SM neutrinos are Dirac.},
