The Energy of n Identical Bosons in a Finite Volume at O(L^{-7})
William Detmold🇺🇸 · Martin J. Savage🇺🇸
Abstract
The volume dependence of the ground-state energy of n identical bosons with short-range interactions in a periodic spatial volume with sides of length L is calculated at order L^{-7} in the large volume expansion. This result will enable a refined determination of the pi^+ pi^+ pi^+ interaction from lattice QCD calculations.
