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…
Three-particle Lellouch-Lüscher formalism in moving frames
Fabian Müller, Jin-Yi Pang, Akaki Rusetsky +1
A manifestly relativistic-invariant Lellouch-Lüscher formalism for the three-particle decays is proposed. Similarly to ref.[1], the formalism is based on the use of the non-relativ…
Spurious poles in a finite volume
Jin-Yi Pang, Martin Ebert, Hans-Werner Hammer +3
Using effective-range expansion for the two-body amplitudes may generate spurious sub-threshold poles outside of the convergence range of the expansion. In the infinite volume, the…
Relativistic-invariant formulation of the NREFT three-particle quantization condition
Fabian Müller, Jin-Yi Pang, Akaki Rusetsky +1
A three-particle quantization condition on the lattice is written down in a manifestly relativistic-invariant form by using a generalization of the non-relativistic effective field…
