In this work the possible dynamical generation of the Inverse Seesaw neutrino mass mechanism from the spontaneous breaking of a gauged U(1) B-L symmetry is investigated. Interestingly, the Inverse Seesaw pattern requires a chiral content such that anomaly cancellation predicts the existence of extra fermions belonging to a dark sector with large, non-trivial, charges under the U(1) B-L. We investigate the phenomenology associated to these new states and find that one of them is a viable dark matter candidate with mass around the TeV scale, whose interaction with the Standard Model is mediated by the Z{\textquoteright} boson associated to the gauged U(1) B-L symmetry. Given the large charges required for anomaly cancellation in the dark sector, the B-L Z{\textquoteright} interacts preferentially with this dark sector rather than with the Standard Model. This suppresses the rate at direct detection searches and thus alleviates the constraints on Z{\textquoteright}-mediated dark matter relic abundance. The collider phenomenology of this elusive Z{\textquoteright} is also discussed.", optnote="WOS:000414811300001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3357), last updated on Tue, 21 Nov 2017 12:30:40 +0000", issn="1029-8479", doi="10.1007/JHEP10(2017)169", opturl="http://arxiv.org/abs/1707.08606", opturl="https://doi.org/10.1007/JHEP10(2017)169", archivePrefix="arXiv", eprint="1707.08606", language="English" }
