论文摘要
Dirac Scotogenic模型提供了一种优雅的机制，该机制解释了小的狄拉克中微子质量和中微子混合，同时可以保护中微子的``diracness''''''中微子'''''''中微子''''''''中微子'''''''在这里，我们探讨了最近在Dirac Scotogent框架中$ W $玻色子质量测量CDF-II测量的现象学意义。我们表明，在暗物质主要是$ su（2）_l $ callar Doublet的情况下，它不能同时满足：（a）暗物质relic密度（b）$ m_w $ assotaly和（c）直接检测约束。但是，与Majoraana Scotogenic模型不同，Dirac版本还具有``Dark Sector'''$ SU（2）_l $ singlet标量。我们表明，如果单元标量表是最轻的深色扇区粒子，即暗物质，那么所有中微子物理和暗物质约束以及来自斜$ s $，$ t $和$ u $参数的约束，可以同时满足CDF-II量的$ W $ BOSON质量。
The Dirac scotogenic model provides an elegant mechanism which explains small Dirac neutrino masses and neutrino mixing, with a single symmetry simultaneously protecting the ``Diracness'' of the neutrinos and the stability of the dark matter candidate. Here we explore the phenomenological implications of the recent CDF-II measurement of the $W$ boson mass in the Dirac scotogenic framework. We show that, in the scenario where the dark matter is mainly a $SU(2)_L$ scalar doublet, it cannot concurrently satisfy: (a) the dark matter relic density (b) the $m_W$ anomaly and (c) the direct detection constraints. However, unlike the Majorana scotogenic model, the Dirac version also has a ``dark sector'' $SU(2)_L$ singlet scalar. We show that if the singlet scalar is the lightest dark sector particle i.e. the dark matter, then all neutrino physics and dark matter constraints along with the constraints from oblique $S$, $T$ and $U$ parameters can be concurrently satisfied for $W$ boson mass in CDF-II mass range.
