对于新发现的玻色子质量异常，可以在不违反其他天体物理和实验约束的情况下解释异常的最简单的暗物质（DM）模型之一是惰性双希格斯模型，其中DM质量（）被发现在其中。在这个模型中，DM通过和的湮灭将产生反质子和伽马射线，并且可以解释先前在这两种粒子中发现的过量。受此启发，我们重新分析了AMS-02反质子和费米LAT银河中心射线数据。对于反质子的分析，新的治疗方法是列入的电荷符号依赖的三维太阳调制模型的约束下，随时间变化的质子数据。我们发现，过量的反质子是更明显的比以前的结果的力场太阳调制模型的基础上。将这种过剩解释为（）的湮灭需要DM质量为（40-60）GeV，速度平均截面为。对于射线数据分析，除了采用广泛使用的空间模板拟合外，我们还采用了数据驱动的光谱模板分析的正交方法。对GeV射线过剩的拟合得到的DM模型参数与通过通道拟合反质子过剩的DM模型参数重叠。的一致性的DM粒子的属性需要考虑的玻色子质量异常，GeV的反质子过剩，和GeV射线过剩表明它们的共同起源。
For the newly discovered-boson mass anomaly, one of the simplest dark matter (DM) models that can account for the anomaly without violating other astrophysical and experimental constraints is the inert two Higgs doublet model, in which the DM mass () is found to be within. In this model, the annihilation of DM viaandwould produce antiprotons and gamma rays, and may account for the excesses identified previously in both particles. Motivated by this, we reanalyze the AMS-02 antiproton and Fermi-LAT Galactic center-ray data. For the antiproton analysis, the novel treatment is the inclusion of the charge-sign-dependent three-dimensional solar modulation model as constrained by the time-dependent proton data. We find that the excess of antiprotons is more distinct than previous results based on the force-field solar modulation model. The interpretation of this excess as the annihilation of() requires a DM mass of(40–60) GeV and a velocity-averaged cross section of. As for the-ray data analysis, besides adopting the widely used spatial template fitting, we employ an orthogonal approach with a data-driven spectral template analysis. The fitting to the GeV-ray excess yields DM model parameters overlapped with those to fit the antiproton excess via thechannel. The consistency of the DM particle properties required to account for the-boson mass anomaly, the GeV antiproton excess, and the GeV-ray excess suggests a common origin of them.
