论文摘要
我们提出了最小$ u（1）_x $型号的超对称扩展，以及新的$ z_2 $ - parity。该模型的显着特征之一与$ u（1）_x $ gauge对称性和R-Parity在TEV级辐射上都被$ Z_2 $ - 右手中微子的VEV辐射。通过分配一个右中微子$ Z_2 $ -ODD奇偶校验，尽管R-Parity被打破了，但它仍然可以保持可行的暗物质（DM）候选。此外，由于$ u（1）_x $ oguge boson（$ z'$）共振，DM遗物丰度获得了增强的歼灭横截面，并且与当前的观察结果一致。我们还发现了在观察到的DM遗物丰度和搜索结果之间存在的互补性，并在大型强子碰撞器（LHC）的$ z^\ prime $ boson共振之间存在，这进一步限制了我们$ u（1）_x $模型的参数空间。最后，我们考虑$ su（5）\ times u（1）_x $肠道扩展，并调查前面提到的互补性。
We propose a supersymmetric extension of the minimal $U(1)_X$ model, along with a new $Z_2$-parity. One of the salient features of this model relates to how both the $U(1)_X$ gauge symmetry and R-parity are broken radiatively at the TeV scale by the VEV of a $Z_2$-even right handed neutrino. By assigning one right-handed neutrino $Z_2$-odd parity, it can remain a viable dark matter (DM) candidate, despite R-parity being broken. Furthermore, the DM relic abundance receives an enhanced annihilation cross section due to the $U(1)_X$ gauge boson ($Z'$) resonance and is in agreement with the current observations. We have also found a complementarity that exists between the observed DM relic abundance and search results for the $Z^\prime$ boson resonance at the Large Hadron Collider (LHC), which further constrains the parameter space of our $U(1)_X$ model. Lastly, we consider a $SU(5)\times U(1)_x$ GUT extension and investigate the complementarities mentioned previously.
