On the Exclusion of Illegal Evidence by the Procuratorial Organs： From Free Proof to Strict Proof

检察机关排除非法证据必须要无缝对接到侦、捕、诉、审等诉讼环节,因为其属于程序性争点以及审判前环节可以采用自由证明的方法,但是由于我国司法机关权力的整体特色和检察机关的法律监督地位而谨慎采用严格证明方法也更加合理,具体有书面审查、口头审查和调取、审查讯问录音录像等方式。检察机关排除非法证据的办案机制以承办人主办、部门讨论和主管领导决定为主,同时还有上下级和部门之间的协作机制。检察机关排除非法证据在监督和控诉的不同方向可能会激化检警冲突和检法冲突。Exclusion of illegal evidence by the procuratorial organs must be seamless link with procedural stages of investigation,arrest,prosecution and trial because it is referred to as procedural issues and the pre- trial step. Thus it can adopt the method of free proof,but owning to the overall entity of three judicial authorities and legal supervision status of procuratorial organs in China,it is reasonable to cautiously adopt strict proof method,specifically by means of written examination,oral examination,and of obtaining,reviewing the video- audio recording of interrogation and so on. The working mechanism of procuratorial organs ＇ exclusion of illegal evidence gives priority to having the undertaker to charging,the department discussing and the manager deciding,adding collaborative mechanism between supervisors and subordinates,among different departments as a supplement.Procuratorial organs＇ excluding illegal evidence in direction to the supervision or accusation may intensify the conflicts between prosecutors and police and between prosecutors and courts.2016年度最高人民检察院检察理论研究一般课题“以审判为中心”背景下的刑事诉讼证据审查（GJ2016C09

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

Prediction of Energy Resolution in the JUNO Experiment

International audienceThis paper presents the energy resolution study in the JUNO experiment, incorporating the latest knowledge acquired during the detector construction phase. The determination of neutrino mass ordering in JUNO requires an exceptional energy resolution better than 3% at 1 MeV. To achieve this ambitious goal, significant efforts have been undertaken in the design and production of the key components of the JUNO detector. Various factors affecting the detection of inverse beta decay signals have an impact on the energy resolution, extending beyond the statistical fluctuations of the detected number of photons, such as the properties of liquid scintillator, performance of photomultiplier tubes, and the energy reconstruction algorithm. To account for these effects, a full JUNO simulation and reconstruction approach is employed. This enables the modeling of all relevant effects and the evaluation of associated inputs to accurately estimate the energy resolution. The study reveals an energy resolution of 2.95% at 1 MeV. Furthermore, the study assesses the contribution of major effects to the overall energy resolution budget. This analysis serves as a reference for interpreting future measurements of energy resolution during JUNO data taking. Moreover, it provides a guideline in comprehending the energy resolution characteristics of liquid scintillator-based detectors

Measurement of integrated luminosity of data collected at 3.773 GeV by BESIII from 2021 to 2024

We present a measurement of the integrated luminosity e+e- of collision data collected by the BESIII detector at the BEPCII collider at a center-of-mass energy of Ecm = 3.773 GeV. The integrated luminosities of the datasets taken from December 2021 to June 2022, from November 2022 to June 2023, and from October 2023 to February 2024 were determined to be 4.995±0.019 fb-1, 8.157±0.031 fb-1, and 4.191±0.016 fb-1, respectively, by analyzing large angle Bhabha scattering events. The uncertainties are dominated by systematic effects, and the statistical uncertainties are negligible. Our results provide essential input for future analyses and precision measurements
