AI 中文摘要
重子数与轻子数的转换对当前宇宙物质-反物质不对称性的动力学产生机制有重要影响。传统观点认为，这类转换源自所谓的电弱 sphaleron 过程。本研究发现，结合合适的标量粒子及其他 TeV 能区新物理，即使电弱 sphaleron 不再活跃，重子-轻子转换仍可保持高效。此外，该场景可解决中子寿命谜题，并预测多核子衰变为多轻子的某些衰变模式。
英文摘要
The conversion between baryon and lepton numbers has a significant impact on the mechanisms for dynamically generating the matter-antimatter asymmetry in the present universe. Under the traditional wisdom, such conversion originates from the so-called electroweak sphaleron processes. In this work we find that in association with a proper scalar and the other TeV new physics, the baryon-lepton conversion can still keep efficient after the electroweak sphalerons are no longer active. Moreover this scenario can provide a solution to the puzzle of neutron lifetime and predict some decay modes of multi-nucleons to multi-leptons.
