Query: BESIII: "charming" physics at an e$^+$e$^-$ collider machine   Despite the successes of the standard model, the non-perturbative dynamics of
the strong interaction are not fully understood yet. Charmonium spectroscopy
serves as an ideal tool to shed light on the dynamics of the strong interaction
such as quark confinement and the generation of hadron masses. The BESIII
collaboration studies extensively the strong interaction and various aspects
that could shed light on physics beyond the standard model via copious
e$^+$e$^-$ collisions at the BESIII/BEPCII facility in Beijing, China, in the
charmonium mass regime. We present a few of the recent results with the
emphasis on charmonium spectroscopy studies using 106$\times10^6$ $\psi^\prime$
events.
