标量双轻子暗物质

Scalar Bilepton Dark Matter

C. A. de S. Pires, P. S. Rodrigues da Silva

摘要:

在这项工作中,我们表明,3-3-1模型的右手中微子有一个自然的弱相互作用的大质量粒子(WIMP)的暗物质候选人。它是一个复杂的标量,质量为几百GeV,携带两个单位的轻子数,标量双轻子。这使它成为一个非常特殊的WIMP,与超对称或额外维度候选者非常不同。此外,虽然我们必须对模型中的几个参数做出一些合理的假设,但为了获得正确的暗物质丰度,不需要进行微调。我们还分析了前景的WIMP直接检测考虑最近和预计的灵敏度的WIMP核子弹性截面的CDMS和氙合作。

英文摘要:

In this work we show that 3-3-1 model with right-handed neutrinos has a natural weakly interacting massive particle (WIMP) dark mater candidate. It is a complex scalar with mass of order of some hundreds of GeV which carries two units of lepton number, a scalar bilepton. This makes it a very peculiar WIMP, very distinct from Supersymmetric or Extra-dimension candidates. Besides, although we have to make some reasonable assumptions concerning the several parameters in the model, no fine tunning is required in order to get the correct dark matter abundance. We also analyze the prospects for WIMP direct detection by considering recent and projected sensitivities for WIMP-nucleon elastic cross section from CDMS and XENON Collaborations.
