宇宙中SUSY离散味对称的可实现性

Realisability of SUSY discrete flavour symmetry in our universe

Hiroaki Nagao, Yusuke Shimizu

摘要:

我们研究了超对称离散味对称模型对宇宙热历史的实现。我们专注于考虑到有限的温度修正之间的黄酮类化合物的赝模量场的演变。我们表明,赝模量flavon占主导地位的能量密度,我们的宇宙和这种支配地位使得至关重要的是难以实现的味道对称模型在我们的宇宙。我们还讨论了超对称离散味对称模型的可能扩展,这可以确保模型与我们宇宙的热历史的一致性。最后,我们展示了一个扩展,实现热膨胀的flavon优势。

英文摘要:

We study the realisation of supersymmetric discrete flavour symmetry models to the thermal history of our universe. We focus on the evolution of the pseudo moduli field among the flavons by taking into account finite temperature corrections. We show that the pseudo moduli flavon dominates the energy density of our universe and this domination makes crucially difficult to realise the flavour symmetry models in our universe. We also discuss possible extensions of the supersymmetric discrete flavour symmetry models which can ensure the consistency of the models with the thermal history of our universe. Finally, we show an extension to realise the thermal inflation by the flavon domination.
