Description
In order to facilitate a connection between the Lagrangian
parameters of the Inverse Seesaw mechanism and low-energy data, we systematically develop new parametrisations of the Yukawa
couplings. Relying on these new parametrisations to explore the parameter space, we discuss the
complementary role of charged lepton flavour violation searches in dedicated facilities, as well as
in lepton colliders (FCC-ee and µTRISTAN). Our results reveal the strong synergy of the different
indirect searches in probing the distinct flavour sectors of the model. In particular, we show that
in the absence of radiative decays $\ell_\alpha\to\ell_\beta\gamma$, sizeable rates for $Z$-penguin dominated observables
could hint at a non-trivially mixed and non-degenerate heavy spectrum.
