Abstract
We study tetraquark resonances with lattice QCD potentials computed for a static pair in the presence of two lighter quarks , the Born-Oppenheimer approximation and the emergent wave method. As a proof of concept we focus on the system with isospin , but consider different relative angular momenta of the heavy quarks . For a bound state has already been predicted with quantum numbers . Exploring various angular momenta we now compute the phase shifts and search for S and T matrix poles in the second Riemann sheet. We predict a tetraquark resonance for , decaying into two mesons, with quantum numbers , mass and decay width .
