abstract

We discuss renormalization of the non-relativistic three-body problem with short-range forces. The problem becomes non-perturbative at momenta of the order of the inverse of the two-body scattering length, and an infinite number of graphs must be summed. This summation leads to a cutoff dependence that does not appear in any order in perturbation theory. We argue that this cutoff dependence can be absorbed in a single three-body counterterm and compute the running of the three-body force with the cutoff. We comment on relevance of this result for the effective field theory program in nuclear and molecular physics.

Short-range production of three bottom mesons

hep-ph · 2025-11-27 · unverdicted · novelty 5.0

Leading-order predictions for three-body point production rates of B and B* meson systems are derived in short-range NREFT from two-body input alone.

Coulomb Corrections to Three-Nucleon Moments

nucl-th · 2026-05-18 · unverdicted · novelty 4.0

Pionless EFT calculations find unexpectedly small O(alpha) Coulomb corrections to three-nucleon magnetic moments and GT matrix elements, yielding a fitted prediction for the proton-proton fusion reduced matrix element of 2.776(331).
