Lüscher equation with long-range forces
Rishabh Bubna, Hans-Werner Hammer, Fabian Müller +3
We derive the modified Lüscher equation in the presence of the long-range force caused by the exchange of a light particle. It is shown that the use of this equation enables one to…

Finite-volume energy shift of the three-nucleon ground state
Rishabh Bubna, Fabian Müller, Akaki Rusetsky
A perturbative calculation of the three-nucleon ground-state energy shift in a finite volume is carried out within the non-relativistic effective theory. The energy shift is evalua…
