Our work aims to investigate the interaction between fermions and dark matter (DM) particles in electron‐positron collisions through interaction of a new massive vector mediator, Z^′. The production of scalar, fermionic, and vector DM pairs via electron‐positron annihilation into the new boson is investigated, evaluating the total cross section in the center‐of‐mass frame. As a result, the possible values of the coupling constants between the DM and the Standard Model of the Elementary Particles particles are mapped according to the exclusion limits obtained by the CMS and ATLAS experiments and the Planck satellite. We show that there are several possibilities for mass ranges of this new massive mediator and for the DM particles, which are not excluded by collider and astrophysical limits.

通过e + e−碰撞研究暗物质的大量矢量介体的性质

我们的工作旨在通过新的大规模矢量介体Z ^'的相互作用来研究费正子与暗物质（DM）粒子在电子-正电子碰撞中的相互作用。研究了通过电子-正电子into灭到新玻色子中产生的标量，费米离子和矢量DM对，从而评估了质心中心的总横截面。结果，根据CMS和ATLAS实验以及普朗克卫星获得的排除极限，绘制了DM与基本粒子标准模型粒子之间耦合常数的可能值。我们表明，这种新型大质量介体和DM颗粒的质量范围存在多种可能性，这些可能性并没有被对撞机和天体物理学的限制所排除。
