Title:Preliminary Study of Three Bosons System in the Finite Volume
Speaker:Dr. Jia-Jun Wu, University of Chinese Academy of Sciences
Abstract:The three-particle quantization condition is partially diagonalized in the center-of-mass frame by using cubic symmetry on the lattice. By using the Bethe-Salpeter equation for particle-dimer scattering, we expand it in the basis functions of different irreducible representations of the octahedral group. Through one toy model, we show that this method can extract the energy eigenvalues in terms of bound and scattering states in the finite volume.Furthermore, we prove that the energy shift in the finite volume upto L^{-6} is cutoff independent.
