摘要

测量了来自光矢量介子的电子对，以研究热致密物质中手性对称性的恢复。J-PARC E16实验旨在测量矢量介子的双电子衰变，特别是φ介子，具有世界上最高的统计数据，以研究它们在原子核中的质谱。我们开发了两级电子识别探测器，由铅玻璃电磁量热计和配备GEMs的气体切伦科夫探测器组成，称为强子盲探测器。在2024年6月，我们完成了所有计划的调试运行，并对探测器进行了首次物理运行的全面验收。我们成功地获得了电子和正电子轨迹的清晰的能量-动量关联，证明了在高速率环境下电子识别技术的建立。

Establishment of the electron identification system for vector meson measurement at J-PARC

Electron pairs from light vector mesons have been measured to study the chiral symmetry restoration in hot and dense matter. The J-PARC E16 experiment aims to measure the di-electron decays of vector mesons, in particular

ϕ

mesons, with the world’s highest statistics to investigate their mass spectrum in nuclei. We developed two-stage electron identification detectors, consisting of a lead-glass electromagnetic calorimeter and a gas Cherenkov detector equipped with GEMs, called a hadron blind detector. In June 2024, we completed all planned commissioning runs with a full detector acceptance for the first physics run. We have succeeded in obtaining a clear energy–momentum correlation of the electron and positron tracks, demonstrating the establishment of the electron identification technique in a high-rate environment.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
