abstract
The standard model of particle physics is a well-established theoretical framework, yet several unresolved issues remain that warrant further experimental and theoretical exploration. In the realm of quark physics, these issues include understanding the nature of quark confinement and elucidating the mechanism linking quarks and gluons to strongly interacting particles within the standard model theory, which may offer insights into the underlying physics mechanisms. These issues inquiries can be addressed through the study of hadrons produced at $e^+e^-$ collisions and decaying to open-charm meson pairs utilizing the capabilities of {\it BABAR}, Belle, BESIII, and CLEO-c experiments, which have yielded valuable insights into nonstandard hadrons in recent decades. This Colloquium examines the contributions of $e^+e^-$ colliders from the {\it BABAR}, Belle, BESIII, and CLEO-c experiments to such studies in the past two decades and discusses future prospects for $e^+e^-$ collider experiments.

QCD sum rules yield lowest masses of 1.53-2.34 GeV for light 1^{--} tetraquarks across isoscalar, isovector and isotensor sectors plus one 1^{-+} isotensor mass of 2.19 GeV.
A coupled-channel framework is developed and fitted to BESIII data on vector charmonium-like states in the 4.1-4.6 GeV range, concluding that coupled-channel effects with dynamically generated poles explain the line shapes.
One-boson-exchange calculations predict multiple loosely bound five-flavor molecular pentaquarks in Ξb('*)D-bar(*) and Ξc('*)B(*) systems with I=0 and listed J^P quantum numbers.
Imposing the SU(3) flavor eigenstate condition on udsc c-bar pentaquarks in a constituent quark model yields two structures matching the masses of P_cs(4338) and P_cs(4459) plus two additional predicted states below the J/ψΛ threshold.
Born-Oppenheimer approximation calculations for doubly heavy hadrons match Gaussian expansion benchmarks at small heavy quark masses but diverge at larger masses, with Slater-type functions overestimating and Gaussian-type underestimating binding energies.
An effective Lagrangian approach calibrated with one adjustable parameter from data reproduces cross sections for K3*(1780), K2(1820), K2(1770) and K4*(2045) and predicts sizable forward-peaked production for additional high-orbital kaons in K-p reactions.
