摘要

-北京光谱仪III (BESIII)使用北京正电子对撞机II (BEPCII)提供的碰撞进行操作，该对撞机位于中国北京高能物理研究所(IHEP)。自2009年以来，BESIII收集了世界上最大的J/ψ， ψ(2S)和ψ(3770)样本。2016年，BEPCII达到了10 cm−2s−1的设计亮度，创造了这种能量状态下e+e−加速器的世界纪录。此外，由于BEPCII可以提供质心能量在2到4.6 GeV之间的碰撞，BESIII有独特的数据集来研究新的奇异XY Z态，开放粲衰，强子光谱和新的物理搜索的性质，在τ -粲能区域没有直接的竞争对手。在本文中，概述了BESIII实验的现状及其最近的结果。

A photo of the status of the BESIII experiment

— The Beijing Spectrometer III (BESIII) operates with the collisions provided by the Beijing Electron Positron Collider II (BEPCII), which is hosted at the Institute of High Energy Physics (IHEP) of Beijing, China. Since 2009, BESIII has collected the world’s largest sample of J/ψ, ψ(2S), and ψ(3770). In 2016 BEPCII has reached the design luminosity of 10 cm−2s−1, setting a world record for e+e− accelerators in this energy regime. Moreover, since BEPCII can provide collisions with center-of-mass energies between 2 and 4.6 GeV, BESIII has unique datasets to investigate the properties of the new exotic XY Z states, open charm decays, hadron spectroscopy and new physics searches, with no direct competitor in the τ -charm energy region. In this paper, an overview on the status of the BESIII experiment and of its more recent results is presented.

期刊介绍： La Rivista del Nuovo Cimento is an international peer-reviewed journal. It publishes monographs in all fields of physics. These monographies aim at presenting the state of the art of topical subjects of relevant interest for the community. Usually, authors are invited and topics suggested by the Deputy Editors-in-Chief, but also spontaneous submissions are examined.
