离散$R$对称性、各种能量标度和引力波

Discrete $R$-symmetry, Various Energy Scales and Gravitational Waves

Gongjun Choi, Weikang Lin, Tsutomu T. Yanagida

摘要:

我们提出了一个超对称模型,其中离散的$R$ -对称性破缺($Z_{6R}$)和宇宙暴胀的能量尺度通常归因于隐藏的$Sp(2)$强动力学的禁闭尺度。除此之外,超对称性破缺标度、希格斯诺质量和右手中微子质量都来源于由CMB观测值推导出的$Z_{6R}$破缺标度.我们将表明,该模型的特点是超对称断裂软质量$m_{\rm soft}\simeq100-1000{\rm TeV}$和再加热温度$T_{\rm rh}\simeq10^{9}{\rm GeV}$。然后,我们讨论了如何这些预测的模型可以测试的引力波的频谱的帮助下,由短暂的宇宙弦存在于再加热时代。

英文摘要:

We present a supersymmetric model where energy scales of a discrete $R$-symmetry breaking ($Z_{6R}$) and cosmic inflation are commonly attributed to the confinement scale of a hidden $Sp(2)$ strong dynamics. Apart from these, SUSY-breaking scale, the Higgsino mass and the right-handed neutrino masses are all shown to stem from $Z_{6R}$ breaking scale inferred from CMB observables. We will show that the model is characterized by the SUSY-breaking soft mass $m_{\rm soft}\simeq100-1000{\rm TeV}$ and the reheating temperature $T_{\rm rh}\simeq10^{9}{\rm GeV}$. Then we discuss how these predictions of the model can be tested with the help of the spectrum of the gravitational wave induced by the short-lived cosmic string present during the reheating era.
