魅力企鹅对BAU
Charmed penguin versus BAU
摘要：
由于标准模型很可能不能解释最近在D介子衰变中观察到的大值CP不对称性，我们提出了第四代夸克-轻子解释，作为副产品的第四代弱混合轻子使宇宙的重子数免于被sphaleron擦除成为可能。简要讨论了第四代对BBN的影响。
英文摘要：
Since the Standard Model most probably cannot explain the large value of CP asymmetries recently observed in D-meson decays we propose the fourth quark-lepton generation explanation of it. As a byproduct weakly mixed leptons of the fourth generation make it possible to save the baryon number of the Universe from erasure by sphalerons. An impact of the 4th generation on BBN is briefly discussed.
