量子引力的重子生成

Baryogenesis by Quantum Gravity

Ken-ji Hamada, Azusa Minamizaki, Akio Sugamoto

摘要:

基于量子引力中共形不变时空到爱因斯坦时空的相变,提出了一种新的重子生成机制。在跃迁处产生了动力学质量约为10^17 GeV的强耦合引力激发。它们最终会衰变成普通物质。作为非粒子物理的一种实现,我们证明了描述激发的引力势与轴向异常引起的非守恒物质流之间的低能有效相互作用可以解释物质在热平衡之外的非对称性.

英文摘要:

A novel mechanism of baryogenesis is proposed on the basis of the phase transition from the conformal invariant space-time to the Einstein space-time in quantum gravity. Strong-coupling gravitational excitations with dynamical mass about 10^17 GeV are generated at the transition. They eventually decay into ordinary matters. As a realization of unparticle physics we show that the low energy effective interactions between the gravitational potential describing the excitation and the non-conserving matter currents by the axial anomalies can explain matter asymmetry out of thermal equilibrium.
