论文摘要
假设暗物质分数$ω_{dm} = 0.27 $和减少的哈勃常数$ h = 0.73 $，我们以前提出的暗物质wimp的质量获得了70 Gev/c $^2 $的值。我们还获得了由$ \langleσ_{ann} v \ rangle = 1.19 \ times 10^{ - 26} $ cm $^3 $/s给出的an灭横截面的值，与矮人球形的当前限制一致。质量和横截面都与Fermi-LAT观察到的银河中心伽马射线的分析以及AMS-02观察到的抗磷脂的分析一致，如果这些数据被解释为由于暗物质歼灭而解释的。据估计，在基于XE的实验中直接检测的旋转无关的横截面估计略高于$ 10^{ - 48} $ cm $^2 $，大概只是在LZ和Xenonnt实验的范围内，具有$ \ gtrsim 1000美元的数据获取。通过向量玻色融合的高能量质子碰撞的生产横截面估计为$ \ sim 1 $ femtobarn，可能在高亮度LHC的范围内，其中$ \ ge 140 $ ge 140 $ GEV缺失的能量伴随两种JET。
Assuming a dark matter fraction $Ω_{DM} = 0.27$ and a reduced Hubble constant $h = 0.73$, we obtain a value of 70 GeV/c$^2$ for the mass of the dark matter WIMP we have previously proposed. We also obtain a value for the annihilation cross section given by $\langle σ_{ann} v \rangle = 1.19 \times 10^{-26} $ cm$^3$/s in the present universe, consistent with the current limits for dwarf spheroidal galaxies. Both the mass and cross-section are consistent with analyses of the Galactic-center gamma rays observed by Fermi-LAT and the antiprotons observed by AMS-02 if these data are interpreted as resulting from dark matter annihilation. The spin-independent cross-section for direct detection in Xe-based experiments is estimated to be slightly above $10^{-48}$ cm$^2$, presumably just within reach of the LZ and XENONnT experiments with $\gtrsim 1000$ days of data taking. The cross-section for production in high-energy proton collisions via vector boson fusion is estimated to be $\sim 1$ femtobarn, possibly within reach of the high-luminosity LHC, with $\ge 140$ GeV of missing energy accompanied by two jets.
