论文摘要
重新审视了标准模型的超对称B-L扩展中最轻的右手Sneutrino暗物质的遗物丰度。我们认为,它可以通过光B-L Higgs玻色子的交换形成结合状态,并获得了大型非扰动的Sommerfeld效应。我们强调,通过这种影响,右撇子Sneutrino的遗物丰富将属于观察限制,而右撇子Sneutrino将仍然是可行的批量命令的可行暗物质候选者,最高为1.5 TEV。
The relic abundance of the lightest right-handed sneutrino dark matter in supersymmetric B-L extension of the standard model is revisited. We argue that it can form a bound state through the exchange of light B-L Higgs boson and a large non-perturbative Sommerfeld effect is obtained. We emphasized that with this effect the relic abundance of right-handed sneutrino will lie within the observational limits and the right-handed sneutrino will remain a viable dark matter candidate of mass order up to 1.5 TeV.
