热大爆炸模型宇宙形成的磁单极机制

A Magnetic-Monopole-Based Mechanism to the formation of the Hot Big Bang Modeled Universe

Qiu-He Peng, Jing-Jing Liu, Chi-Kang Chou

摘要:

有一些粒子物理学理论超越了所谓的“标准宇宙学模型”,预测磁单极子的存在。磁单极子的发现将是高能物理学中一个令人难以置信的突破。早期宇宙中存在的宇宙粒子已经被大统一理论推测和预测。如果存在重子,则大统一规范理论的重子数破坏效应将不能抑制统一质量的幂次倒数。因此,MM催化核子衰变是一种典型的强相互作用。这种现象是由于边界条件必须施加在MM费米子场的核心。我们提出了一个可能的机制来解释热大爆炸宇宙学的形成。我们模型中的主要成分是由磁单极子催化的核子衰变(即,Rubakov-Callan效应)。结果表明,热大爆炸是自然发展的,因为Rubakov-Callan效应引起的光度远大于Eddington光度(即,$L_m>10^4L_{\rm{Edd}}$)。

英文摘要:

There are some particle physics theories that go beyond the so-called "standard cosmological model" to predict the existence of magnetic monopoles\,(MMs). The discovery of magnetic monopoles would be an incredible breakthrough in high-energy physics. The existence of MMs in the early Universe has been speculated and anticipated from Grand Unified Theory. If MMs exist, the inverse powers of the unification mass will not suppressed the baryon number violating effects of grand unified gauge theories. Therefore, MM catalyzing nucleon decay is a typical strong interaction. This phenomenon is due to the boundary conditions that must be imposed on the core of MM fermion fields. We present a possible mechanism to explain the formation of the Hot Big Bang Cosmology. The main ingredient in our model is nucleon decay catalyzed by magnetic monopoles (i.e., the Rubakov-Callan effect). It is shown that Hot Big Bang developed naturally, because the luminosity due to the Rubakov-Callan effect is much greater than the Eddington luminosity (i.e., $L_m>10^4L_{\rm{Edd}}$).
