CEPC/FCC可产生数量在万亿级别的Z玻色子，千万级别的W粒子，百万级别的Higgs粒子，经升级后也可产生百万级别的顶夸克，而Z玻色子有70%的概率会衰变为一对正反夸克，以及3%的概率衰变到一对Tau轻子。因此，CEPC在味物理研究领域具有巨大的潜力。
为了量化CEPC在味物理上的科学潜力、明确其比较优势，并通过优化设计以最大化CEPC的科学产出，CEPC预研团队对CEPC上的味物理潜力进行了一系列研究。
2019年，CEPC研究小组提出撰写味物理白皮书的计划，以汇总上述关键信息；并于近期完成了一阶段的味物理白皮书（Phase-I）的初稿。目前的白皮书初稿覆盖了稀有b衰变、CP破坏、谱学研究等内容。
必须指出的是，味物理研究的范畴极为宽广，目前的白皮书中还有若干漏项，而CEPC加速器本身的各项参数也在逐步优化，将于今年（2023年）发布CEPC技术设计报告。CEPC上可进行的味物理研究领域中尚未被目前白皮书覆盖的内容，将通过未来的二阶段预研（Phase-II study）加以覆盖。
本页面的建立是为了搜集CEPC味物理研究人员和课题的信息。如果您有兴趣参与CEPC未来的味物理研究中来，并支持目前CEPC味物理，请在本页面注册；同时我们会将您列为本白皮书的作者。
目前，此白皮书的初稿还有有部分编辑润色工作尚未完成，待此部分工作完成后，我们计划在近期上传至arXiv。白皮书现有版本已附在本页面。
同时，如果您对此白皮书初稿或对CEPC味物理研究有建议，请填写本页面下的调查表，我们将记录并考虑您的建议。如果您有其他希望探讨的问题，也欢迎致信本页面所列联系人。
CEPC/FCC can produce trillions of Z bosons, tens of millions of W bosons, millions of Higgs bosons, and, potentially, about a million top quarks. Z bosons decay with a 70% probability to quark-antiquark pairs and a 3% probability to a pair of Tau leptons. Therefore, CEPC has great potential in the field of flavor physics studies.
In order to quantify the scientific potential of CEPC in flavor physics, clarify its comparative advantages, and maximize the scientific output of CEPC by optimizing the detector design, the CEPC R&D team conducted a series of studies on the physics potential of flavor on CEPC.
In 2019, the CEPC study group proposed a plan to write a white paper on flavor physics to summarize the aforementioned key information; and recently completed the first draft of the Phase-I White Paper on Flavor Physics. The current draft of the white paper covers rare B decay, CP violations, spectroscopy studies, etc.
It must be pointed out that the scope of flavor physics research is extremely broad, there are still some omissions in the current white paper, and the parameters of the CEPC accelerator itself are still being optimized, the CEPC technical design report (TDR) will be released this year (2023). What is available at CEPC that is not yet covered by the current white paper will be covered by future Phase-II studies.
This indico page was created to collect information on CEPC flavor physics researchers and research topics. If you are interested in participating in and support CEPC's future flavor physics studies, please register on this page; We will also list you as the author of this white paper.
At present, there are still some editorial work to be done, and we plan to upload this White Paper to arXiv in the next couple of weeks. The current version of the white paper was attached in this indico page.
In the meantime, if you have any suggestions for this white paper draft, please fill out the survey in this page and we will consider your suggestions. If you have other questions that would like to discuss, please contact us via the emails listed in this indico page.
