Highlights from BESIII

Abstract

We present a selection of recent results from the BESIII collaboration, including both charmonium and $D$ meson physics. We first discuss the observation of a charged, charmonium-like state, the $Z_c(3900)$. Conventional charmonium topics include a search for lepton flavor violation, studies of $\chi_{cJ} \to \gamma\gamma$ decays, and mass and width determinations for the $h_c$, $\eta_c(1S)$, and $\eta_c(2S)$. We finish with results on the decay constant $f_D$ from $D^+ \to \mu^+ \nu$ and on form-factors in $D^0 \to K^- e^+ \nu, \pi^- e^+ \nu$.
