戈德斯通费米子暗物质

Goldstone Fermion Dark Matter

Brando Bellazzini, Csaba Csaki, Jay Hubisz, Jing Shao, Philip Tanedo

摘要:

我们认为,弱尺度戈德斯通玻色子的费米子超伴子可以是一个天然的WIMP候选者。这种“戈德斯通费米子”的p波湮灭成成对的戈德斯通玻色子自动产生正确的遗迹丰度,而由于与标准模型的耦合被抑制,XENON 100的直接探测边界被规避。此外,它能够避免间接的检测约束,因为相关的s波湮灭是小的。Goldstone超多重态的相互作用可以导致非标准的Higgs衰变和新的对撞机现象。

英文摘要:

We propose that the fermionic superpartner of a weak-scale Goldstone boson can be a natural WIMP candidate. The p-wave annihilation of this `Goldstone fermion' into pairs of Goldstone bosons automatically generates the correct relic abundance, whereas the XENON100 direct detection bounds are evaded due to suppressed couplings to the Standard Model. Further, it is able to avoid indirect detection constraints because the relevant s-wave annihilations are small. The interactions of the Goldstone supermultiplet can induce non-standard Higgs decays and novel collider phenomenology.
