Three particles in a finite volume

Polejaeva, Kathryn, Rusetsky, Akaki

Understand

Within the non-relativistic potential scattering theory, we derive a generalized version of the L\"uscher formula, which includes three-particle inelastic channels.

  • Faddeev equations in a finite volume are discussed in detail.
  • It is proved that, even in the presence of the three-particle intermediate states, the discrete spectrum in a finite box is determined by the infinite-volume elements of the scattering S-matrix up to corrections, exponentially suppressed at large volumes.
