F-SU(5)

F-SU(5)

Jing Jiang, Tianjun Li, Dimitri V. Nanopoulos, Dan Xie

摘要:

我们从F理论出发构造了三个翻转的SU(5)XU(1)_X模型,并从自由费米子弦模型出发考虑了两个翻转的SU(5)XU(1)_X模型.为了实现F理论模型中的解耦方案和自由费米子模型中的弦尺度规范耦合统一,我们引入了可以在大型强子对撞机上观察到的TeV尺度的矢量粒子。我们研究规范耦合统一,并发现质子衰变是在未来的超神冈实验的范围内。在这些模型中,可以解决双三重态分裂问题和双三重态问题,中微子质量和混合可以用双跷跷板机制解释,重子不对称性可以用轻子创生得到,混合暴胀可以实现,宇宙原初密度涨落可以正确地产生。

英文摘要:

We construct three flipped SU(5) X U(1)_X models from F-theory, and consider two such models from free fermionic string model building. To achieve the decoupling scenario in F-theory models and the string-scale gauge coupling unification in free fermionic models, we introduce vector-like particles at the TeV scale that can be observed at the Large Hadron Collider. We study gauge coupling unification, and find that proton decay is within the reach of the future Hyper-Kamiokande experiment. In these models, the doublet-triplet splitting problem and monopole problem can be solved, the neutrino masses and mixings can be explained via the double seesaw or seesaw mechanism, the observed baryon asymmetry can be obtained through leptogenesis, the hybrid inflation can be realized, and the correct cosmic primodial density fluctuations can be generated.
