论文摘要
Scotogenic模型构成了对中微子群众产生和暗物质神秘的有吸引力的解决方案。在这项工作中，我们考虑了自发破坏Lepton数字的Scotogenic模型的版本。在此范围内，我们使用额外的单线标量扩展了Scotogent模型的粒子含量，该标量获得了非零的真空期望值并破坏了全局Lepton数字对称性。结果，粒子光谱中出现了无质量的金石玻色子（Mapon）。我们讨论了Magroon的存在如何在风味和暗物质观察物上修饰现象学。我们专注于典型的暗物质候选者，并分析其直接检测和间接检测的遗物丰度和前景。
Scotogenic models constitute an appealing solution to the generation of neutrino masses and to the dark matter mystery. In this work we consider a version of the Scotogenic model that breaks lepton number spontaneously. At this scope, we extend the particle content of the Scotogenic model with an additional singlet scalar which acquires a non-zero vacuum expectation value and breaks a global lepton number symmetry. As a consequence, a massless Goldstone boson, the majoron, appears in the particle spectrum. We discuss how the presence of the majoron modifies the phenomenology, both in flavor and dark matter observables. We focus on the fermionic dark matter candidate and analyze its relic abundance and prospects for both direct and indirect detection.
