摘要:

在狄拉克中微子超对称模型中,当软中微子三线性参数较大时,最轻的中微子可以成为热暗物质的候选者。我们专注于场景的混合sneutrino的质量是GeV的顺序和暗物质直接检测的灵敏度是弱的。我们调查的模型参数空间,包括真空稳定性界的唯象约束。我们表明,允许的区域可以探索通过测量希格斯玻色子的性质在未来的对撞机实验。

英文摘要:

In supersymmetric models with Dirac neutrinos, the lightest sneutrino can be an excellent thermal dark matter candidate when the soft sneutrino trilinear parameter is large. We focus on scenarios where the mass of the mixed sneutrino is of the order of GeV and sensitivity of dark matter direct detection is weak. We investigate phenomenological constraints on the model parameter space including the vacuum stability bound. We show that the allowed regions can be explored by measuring Higgs boson properties at future collider experiments.
