Finite-volume energy shift of the three-nucleon ground state
Rishabh Bubna, Fabian Müller, Akaki Rusetsky
Abstract
A perturbative calculation of the three-nucleon ground-state energy shift in a finite volume is carried out within the nonrelativistic effective theory. The energy shift is evaluated up to and including $O({L}^{\ensuremath{-}6})$, where $L$ is the size of a cubic box. The convergence of the perturbative series at physical values of the scattering lengths is studied numerically.
