Abstract: There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BESIII and B factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835) meson state at BESIII, as well as the threshold measurements of charm mesons and charm baryons. We present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BESIII during the remaining operation period of BEPCII. This survey will help in the optimization of the data-taking plan over the coming years, and provides physics motivation for the possible upgrade of BEPCII to higher luminosity.

TL;DR: A detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BESIII over the remaining lifetime of BEPCII operation is presented in this article.

TL;DR: This is the first candidate for a charged hidden-charm tetraquark with strangeness, decaying into D_{s}^{-}D^{*0} and D-D^{0}.

TL;DR: In this paper, the first observation of spin polarization of Lambda and Lambda$ hyperons from the coherent production in the $J/\psi\to Lambda\bar\Lambda$ decay was reported.

TL;DR: In this paper, the authors reported the measurement of ΔΦ = 42.4 ± 0.5° using Λ→πππ$^{−}$ and Λ ≥ 0.004, a precise direct test of charge parity symmetry violation in Λ decays.
