“…Instead, a subtraction point is introduced in the kernel of the LS equation [8] to reach a finite T matrix. Our research group has considered singular contact interactions in the context of nuclear [5,6,9,10], atomic, and general physics [11,12]. In such works, within specific renormalization procedures applied to few-body systems, scaling limits and correlations between low-energy observables emerge as a consequence of using singular contact (zero-range) interactions.…”

We present a methodology to renormalize the nucleon-nucleon interaction in momentum space, using a recursive multiple subtraction approach that prescinds from a cutoff regularization, to construct the kernel of the scattering equation. The subtracted scattering equation is solved with the next-leading-order and nextto-next-leading-order interactions. The results are presented for all partial waves up to j = 2, fitted to lowenergy experimental data. In this renormalization group invariant approach, the subtraction energy emerges as a renormalization scale and the momentum associated with it comes to be about the QCD scale ( QCD ), irrespectively to the partial wave.

“…The point is that there is already a series of works [2]- [4] (also see Refs. [5]- [7]) showing that the excited state of the 4 He trimer is initiated by the Efimov effect [8]. In these works, various versions of the 4 He-4 He potential were employed.…”
