      "value": "We implement a minimal linear seesaw model (LSM) for addressing the Quasi-Dirac (QD) behaviour of heavy neutrinos, focusing on the mass regime of M  N  \u2272 M  W . Here we show that for relatively low neutrino masses, covering the few GeV range, the same-sign to opposite-sign dilepton ratio, R  \u2113\u2113 , can be anywhere between 0 and 1, thus signaling a Quasi-Dirac regime. Particular values of R  \u2113\u2113  are controlled by the width of the QD neutrino and its mass splitting, the latter being equal to the light-neutrino mass m  \u03bd  in the LSM scenario. The current upper bound on m  \u03bd1 together with the projected sensitivities of current and future |U  N \u2113 |2 experimental measurements, set stringent constraints on our low-scale QD mass regime. Some experimental prospects of testing the model by LHC displaced vertex searches are also discussed."
