Sukanta Dutta, Ashok Goyal, Lalit Kumar Saini

摘要:

标准模型(SM)自旋零单线态通过其双玻色子衰变通道被约束,通过类矢量夸克(VLQ)环在LHC($\sqrt{s}$ = 13 TeV)诱导的有效耦合。这些自旋零共振,然后被认为是门户网站的标量,矢量或费米暗物质粒子相互作用的SM规范玻色子。我们发现,该模型是验证从大型强子对撞机的数据和宇宙学,间接和直接检测实验的标量,矢量和费米子DM质量大于300 GeV和VLQ质量$\ge$ 400 GeV,相应的三个选择的门户群众分别为270 GeV,500 GeV和750 GeV的可观的范围内的观测。

英文摘要:

Standard model (SM) spin-zero singlets are constrained through their di-Bosonic decay channels via an effective coupling induced by a vector-like quark (VLQ) loop at the LHC for $\sqrt{s}$ = 13 TeV. These spin-zero resonances are then considered as portals for scalar, vector or fermionic dark matter particle interactions with SM gauge bosons. We find that the model is validated with respect to the observations from LHC data and from cosmology, indirect and direct detection experiments for an appreciable range of scalar, vector and fermionic DM masses greater than 300 GeV and VLQ masses $\ge$ 400 GeV, corresponding to the three choice of portal masses 270 GeV, 500 GeV and 750 GeV respectively.
