Findings

Resonance masses and decay widths extracted from lattice QCD.

Identification of states near thresholds such as $Z_c^+(3900)$ and $X(3872)$.

Insights into meson structure and decay mechanisms from lattice results.

Abstract

Recent results on meson spectroscopy from lattice QCD are reviewed. The emphasis is on interesting states near thresholds like $Z_c^+(3900)$, $X(3872)$ and $D_{s0}^*(2317)$. Another focus is on the meson resonances in light, strange and charm sector, where the resonance masses as well as the strong decay widths are extracted from the lattice.
