摘要

在这个过程中,我将讨论暗物质的本质与中微子质量产生有关的可能性。重点是标准模型的扩展,其中光中微子质量是辐射产生的,我们研究了暗物质候选物质的特性,该候选物质通过负责中微子质量辐射起源的相同对称性而变得稳定。此外,所研究的模型提出了一种暗物质候选物质,它既可能是中性标量,也可能是费米子。我将讨论这两种情况的现象学,研究允许再现观测到的暗物质丰度的参数空间。我还将评论通过间接探测探针和对撞机进行的直接探测实验中预期的信号。

An extensive study of dark matter and neutrino phenomenology in the Triplet + Singlet Scotogenic Model
In this proceeding, I will address the possibility that the nature of dark matter is associated with neutrinomass generation. Focusing on an extension of the StandardModelwhere the light neutrino masses are generated radiatively, we study the properties of a dark matter candidate which is made stable by the same symmetry responsible for the radiative origin of neutrino masses. Also, the model studied proposes a dark matter candidate that could be both a neutral scalar or a fermion. I will discuss the phenomenology of both scenarios, studying the parameter space which allows to reproduce the observed dark matter abundance. I will also comment on the expected signals in direct detection experiments, via indirect detection probes and at colliders.
