Charmoniumlike Channels $1^{+}$ with Isospin $1$ from Lattice and Effective Field Theory

Mitja Sadl, Sara Collins, Zhi-Hui Guo +3

Many exotic charmoniumlike mesons have already been discovered experimentally, of which the $Z_c$ mesons with $I=1$ are prominent examples. We investigate $J^{PC}=1^{+\pm }$ states…
