论文摘要

我们考虑通过$ s $波的过程将一个弱相互作用的巨大粒子(WIMP)暗物质(WIMP)暗物质(DM)歼灭,包括SM中微子,包括SM中微子,并通过使用CMB的数据中的数据和cmb.-ray and cmbay and cmbay and cmbay and cmbay and com-ray and com-ray and com-ray and con and and and andionation cross $ \ langle $ \ langle $ \ langle cross cross cross截面的上限。对于所有相关天体物理参数的保守选择,我们获得了$ 10^{ - 23} -10^{ - 25} \,{\ rm cm}^3 {\ rm s}^{\ rm s}^{ - 1} $的上限mev} -100 \,{\ rm tev} $,因此使整个质量范围与观察到的遗物密度一致。我们分析中的一个重要输入是,假设热wimps可以与SM中微子有显着的耦合。

We consider a weakly interacting massive particle (WIMP) dark matter (DM) annihilating into all possible Standard Model (SM) particle pairs, including the SM neutrinos, via $s$-wave processes and derive the branching ratio independent upper limit on the total annihilation cross-section $\langle σv \rangle$ using the data of CMB, gamma-ray, cosmic-ray and several neutrino observations. For conservative choices of all relevant astrophysical parameters, we obtain upper limits of $10^{-23}-10^{-25}\,{\rm cm}^3{\rm s}^{-1}$ on the total $\langle σv \rangle$ for the WIMP mass range $10\,{\rm MeV}-100\,{\rm TeV}$, thus making the entire mass range consistent with the observed relic density. An important input that goes into our analysis is the assumption that thermal WIMPs can have significant coupling to the SM neutrinos.
