Description
We selected candidate events for production of the exotic charged charmonium-like states $Z_c^{\pm}(3900)$ decaying to $ J/\psi\pi^{\pm}$ and $X(3872)$ decaying to $J/\psi\pi^{\pm}\pi^{\mp}$. We use 10.4 $\rm fb^{−1}$ of $p\bar p$ collisions recorded by the D0 experiment at the Tevatron collider at $\sqrt s=$1.96 TeV. We measure the $Z_c$ mass and natural width using subsample of candidates originating from semi-inclusive weak decays of b-flavored hadrons and search for the $Z_c$ prompt production. We also study various properties of the $X(3872)$ production that are compared to $\psi(2S)\to J/\psi\pi^{\pm}\pi^{\mp}$ production.
