论文摘要
我们讨论了在未来的$ e^{+} e^{ - } $ colliders上检测旋转0、1和1/2暗物质(DM)的可能性。此处考虑的模型是简单,一致和可重大的场理论,可提供正确的DM丰度并满足直接检测,间接检测和对撞机的约束。本文的目的是验证通过测量$ e^{+} e^{ - } \ to z+\ ldots \,$在将来的$ e^{+e^{+e^{+} e^{ - } $ colliders的$ e^{+\ ldots \,$ colliders $ e^{+\ ldots \,$。我们专门研究在$ \ sqrt {s} = 250〜 \ text {gev} $下运行的ILC的情况,但是我们的结果也适用于FCC-EE和CEPC Colliders。对于每个模型,对参数最大化的横截面进行了计算,并将其与预期的95%CL横截面限制进行了比较。事实证明,接近$ 2 m _ {\ text {dm}} \ simeq m_ {1,2} $共振,其中$ m_ {1} $和$ m_ {2} $是Sm higgs boson和非标准的higgs boson群体,分别是型号的型号。已经特别注意计算$ m_ {1} \ simeq m_ {2} $的区域的横截面。
We discuss possibility to detect spin 0, 1 and 1/2 dark matter (DM) at future $e^{+} e^{-}$ colliders. The models considered here are simple, consistent and renormalizable field theories, that provide correct DM abundance and satisfy direct detection, indirect detection and collider constraints. The intention of this paper was to verify to what extend it might be possible to disentangle models of different DM spins by measurement of the cross section for $e^{+} e^{-} \to Z + \ldots\,$ at future $e^{+} e^{-}$ colliders. We specialize to the case of the ILC operating at $\sqrt{s} = 250~\text{GeV}$, however our results apply as well for the FCC-ee and the CEPC colliders. For each model the cross section maximized with respect to parameters was calculated and compared to the expected 95% CL cross-section limits estimated for the ILC. It turned out that near $2 m_{\text{DM}}\simeq m_{1,2}$ resonances, where $m_{1}$ and $m_{2}$ are the SM Higgs boson and a non-standard Higgs boson masses, respectively, there exist substantial regions where the models are testable. A special attention has been payed to calculation of the cross section in the region where $m_{1}\simeq m_{2}$.
