We study all extensions of the standard model (SM) with a vector dark matter (VDM) candidate which can explain the peak structure observed recently by the DAMPE experiment in the electron–positron cosmic ray spectrum. In this regard, we consider all leptophilic renormalizable VDM-SM interactions through scalar, spinor, and vector mediators. We show that only two out of six possible models could produce a DAMPE signal by annihilation of VDM with a mass of about 1.5 TeV in a nearby subhalo, whilst simultaneously satisfying the constraints from DM relic density, direct/indirect detection, and the collider bounds. These two models have a scalar/pseudoscalar mediator ϕ with M ϕ ∈ [1500, 3000] GeV.

亲脂性载体暗物质中的DAMPE过量：与模型无关的方法

我们用矢量暗物质（VDM）候选物研究标准模型（SM）的所有扩展，这可以解释DAMPE实验在电子-正电子宇宙射线光谱中最近观察到的峰结构。在这方面，我们考虑了通过标量，旋转子和载体介体进行的所有亲脂性可重新规范化的VDM-SM相互作用。我们表明，在六个可能的模型中，只有两个模型可以通过消灭附近亚晕中质量约为1.5 TeV的VDM来产生DAMPE信号，同时满足DM遗迹密度，直接/间接检测和对撞机边界的约束。这两个模型都有一个标量/伪标量介体ϕ，其M∈[1500，3000] GeV。
