论文摘要
无论是什么暗物质，它都必须是扩展的洛伦兹集团或另一个不可约的统一表示。在这里，我们发展了质量尺寸的形式主义，一个速度和旋转一半的玻色子，并表明它们提供了自然的暗物质候选者。通过施工，它们在时空翻译和提升下是协变量的。然而，结合旋转对称性是不平凡的，需要引入两个倍的脱位性，从而使颗粒和抗颗粒的自由度从两个到四个增加一倍。借助Wigner堕落，我们具有明确的质量维度理论，一个旋转一半的旋转场，与狄拉克场有物理上不同。他们是本地的，洛伦兹的协变量，并且具有积极的自由汉密尔顿人。开发的框架还具有解决宇宙恒定问题并提供暗能量的潜力。
Whatever dark matter is, it must be one irreducible unitary representation of the extended Lorentz group or another. We here develop a formalism of mass dimension one fermions and bosons of spin one half, and show that they provide natural dark matter candidates. By construction, they are covariant under space-time translations and boosts. However, incorporating the rotational symmetry is non-trivial and requires introducing a two-fold Wigner degeneracy thus doubling the degrees of freedom for particles and anti particles from two to four. With Wigner degeneracy, we have a well-defined theory of mass dimension one fields of spin one half that are physically distinct from the Dirac field. They are local, Lorentz covariant and have positive definite free Hamiltonians. The developed framework also has the potential to resolve the cosmological constant problem, and supply dark energy.
