M. Adeel Ajaib, Ilia Gogoladze, Qaisar Shafi, Cem Salih Un

摘要:

我们重新讨论了一类具有t-b-tau Yukawa耦合统一条件的超对称SO(10)模型,重点讨论了Higgs质量的预测.我们讨论在这个模型中的定性特征,导致希格斯粒子质量预测接近125 GeV。我们展示了这两个不同的计算包,Isajet和SuSpect,也表明,他们在这个模型的参数空间中产生类似的全球功能。我们发现,t-b-tau汤川耦合统一更喜欢CP奇希格斯质量m_{A}的值为600 GeV左右,与所有彩色sparticle质量超过3 TeV。我们还简要讨论了通过正在进行的和计划的直接暗物质探测实验来测试这种情况的前景。在t-b-tau Yukawa统一的这类模型中,中性伴子暗物质粒子很重(m_{ \tilde χ_1^{0}} \gtrsim 400 \rm \ GeV),它与一个stau共湮灭,产生正确的残余丰度。

英文摘要:

We revisit a class of supersymmetric SO(10) models with t-b-tau Yukawa coupling unification condition, with emphasis on the prediction of the Higgs mass. We discuss qualitative features in this model that lead to a Higgs mass prediction close to 125 GeV. We show this with two distinct computing packages, Isajet and SuSpect, and also show that they yield similar global features in the parameter space of this model. We find that t-b-tau Yukawa coupling unification prefers values of the CP-odd Higgs mass m_{A} to be around 600 GeV, with all colored sparticle masses above 3 TeV. We also briefly discuss prospects for testing this scenario with the ongoing and planned direct dark matter detection experiments. In this class of models with t-b-tau Yukawa unification, the neutralino dark matter particle is heavy (m_{\tildeχ_1^{0}} \gtrsim 400 \rm \ GeV), which coannihilates with a stau to yield the correct relic abundance.
