Estimating Consequences of 3-Body Forces

TL;DR

This paper investigates the effects of three-body forces in nuclear physics, emphasizing the importance of renormalization for observable independence, with implications for neutron capture processes.

Contribution

It introduces a method to classify three-body force strengths ensuring observable independence through renormalization at each order.

Findings

Renormalization ensures cut-off independence of observables.

Three-body force classification impacts neutron capture calculations.

Surprising results highlight the significance of proper force strength estimation.

Abstract

Classifying the strengthes of three-body forces 3BFs with the condition that observables must be cut-off independent, i.e. renormalised at each order, leads to surprising results with relevance for example for thermal neutron capture on the deuteron. Details and a better bibliography in Ref. [1].
