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 $D^0\to K^{-}{e}^{+}\nu ,{\pi }^{-}{e}^{+}\nu$.
