研治中国社会经济史之路——访杨际平先生

杨际平先生是当代著名的中国古代社会经济史和敦煌出土文书研究领域的专家,在中国古代土地制度、赋役制度、财政史等方面有突出贡献。近年来杨先生对北朝隋唐时期的田制和汉唐赋役制度等问题有新的思考和研究。应本刊编辑部之约,杨先生结合新近研究、反思,畅谈了数十年来研治中国社会经济史的历程和体悟

福建戴云山区村落建设生态博物馆的可行性探讨——以永泰县珠峰村为例

生态博物馆的理念传入我国已有三十余年,以往我国建立的生态博物馆大都显现出以少数民族及他们的文化遗产为保护对象、绝大多数建立在西部偏远地区的两大特点。随着我国生态博物馆理念...厦门大学哲学社会科学繁荣计划资助(项目经费代码0640-Y03101

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
