Query: Neutrino masses and gauged $U(1)_\ell$ lepton number   We investigate the tree-level neutrino mass generation in the gauged
$U(1)_\ell$ lepton model recently proposed by us [arXiv:1805.10382]. With the
addition of one Standard Model(SM) singlet, $\phi_1(Y=0, \ell=1)$, and one SM
triplet scalar, $T(Y=-1,\ell=0)$, realistic lepton masses can be accommodated.
The resulting magnitude of neutrino mass is given by $\sim v_t^3/v_L^2$, where
$v_t$ and $v_L$ are the vacuum expectation values of $T$ and $\phi_1$,
respectively, and it is automatically of the inverse see-saw type. Since $v_L$
is the lepton number violation scale we take it to be high, i.e. ${\cal O}
\gtrsim (\mbox{TeV})$. Moreover, the induced lepton flavor violating processes
and the phenomenology of the peculiar triplet are studied. An interesting
bound, $0.1\lesssim v_t\lesssim24.1$ GeV, is obtained when taking into account
the neutrino mass generation, $Br(\mu\rightarrow e \gamma)$, and the limits
from oblique parameters, $\Delta S$ and $\Delta T$. Collider phenomenology of
the SM triplets is also discussed.
