A lattice model of heavy-light three-body system

Understand

We present a study of a $1+1$ dimensional heavy-light three-body system in finite volume.

• The heavy-light system is simulated by a coupled-channel $\phi^4$ type lattice model, and both ground state and excited states of multiparticle energy spectra are measured on various lattices.
• The lattice simulation data analysis is performed based on variational approach.
