Recent XYZ results at BESIII

Abstract

BESIII experiment has collected about 20 fb${}^{-1}$ luminosity data between $\sqrt{s}=3.8$ and 4.7 GeV via $e^{+}{e}^{-}$ collision. In this talk, we present the recent $XYZ$ results at BESIII, including mass and width measurements of $Y(4220)$, search for $Y$ states with rare decay modes, isospin parity determination of $Z_c^0(3900)$ as well as the mass and width determination, and search for new decay modes of $X(3872)$.
