Modified Lüscher zeta-function and the modified effective range expansion in the presence of a long-range force
Rishabh Bubna, Hans-Werner Hammer, Bai-Long Hoid +3
An efficient numerical algoritm is proposed for the calculation of the modified Lüscher zeta-function in the presence of a long-range force. Using the formalism developed in Ref.~\…
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…
Three-body spectrum in a finite volume: the role of cubic symmetry
M. Döring, H. -W. Hammer, M. Mai +3
The three-particle quantization condition is partially diagonalized in the center-of-mass frame by using cubic symmetry on the lattice. To this end, instead of spherical harmonics,…
