Review on Hadron Spectroscopy

Abstract

I review some of the lattice results on spectroscopy and resonances in the past years. For the conventional hadron spectrum computations, focus has been put on the isospin breaking effects, QED effects, and simulations near the physical pion mass point. I then go through several single-channel scattering studies within Lüscher formalism, a method that has matured over the past few years. The topics cover light mesons and also the charmed mesons, with the latter case intimately related to the recently discovered exotic $XYZ$ particles. Other possible related formalisms that are available on the market are also discussed.
