TL;DR: In this article, the authors provide detailed discussion on important topics in tau-charm physics that will be explored during the next few years at \bes3. Both theoretical and experimental issues are covered, including extensive reviews of recent theoretical developments and experimental techniques.

TL;DR: In order to improve the charged particle identification capability, end-cap time-of-flight (ETOF) detector of the Beijing Spectrometer (BESIII) has been upgraded with multi-gap resistive plate chamber (MRPC) technology, aiming at an overall time resolution of 80 ps for minimum-ionization particles to extend the K/676 $$\pi $$¯¯ separation (2 petertodd $$\sigma $$¯¯¯¯ ) momentum range to 1.4 GeV/c as discussed by the authors.

TL;DR: In this paper, the end cap time of flight at Beijing Spectrometer is upgraded with multi-gap resistive plate chamber technology in order to improve the charged particle identification capability.
