Ítem Fermion dark matter in the vector scotogenic model: a survey of signatures(Springer Nature, 2024-12) Areyuna, Paulo C.; Zamora-Saa, Jilberto; Zerwekh, Alfonso R.In this work, we have studied the vector scotogenic model in the context of the dark matter problem. Due to unitarity considerations, we have focused on the scenario with fermion dark matter, finding out that co-annihilations play a fundamental role in achieving dark matter relic abundance. Moreover, the coannihilation effects allow to separate the parameter space into two regions with different phenomenology. In addition, we have studied the detection prospects of these regions separately, focusing on signatures that can appear in lepton flavor violating decays, indirect and direct searches, and the production of these new particles at collider facilities. © The Author(s) 2024.Ítem Fermion dark matter in the vector scotogenic model: a survey of signatures(Springer Nature, 0024-12) Areyuna, Paulo C; Zamora-Saa, Jilberto; Zerwekh, Alfonso R.In this work, we have studied the vector scotogenic model in the context of the dark matter problem.

We study the production of these exotic leptons with the Same Flavor Opposite Sign standard lepton pair, and jets, considering Drell-Yan and Vector Boson Fusion as independent cases. We find that for the latter, the dilepton angular distribution is different enough from the background to use it as a smoking-gun for our model. Based on this fact, we establish limits on the parameter space considering previous experimental searches in this final state.
