Abstract

In relativistic Hamiltonians the two-nucleon interaction is expressed as a sum of ṽij, the interaction in the Pij=0 rest frame, and the ‘‘boost interaction’’ δv(Pij) which depends upon the total momentum Pij and vanishes in the rest frame. The δv can be regarded as a sum of four terms: δvRE, δvLC, δvTP, and δvQM; the first three originate from the relativistic energy-momentum relation, Lorentz contraction, and Thomas precession, while the last is purely quantum. The contributions of δvRE and δvLC have been previously calculated with the variational Monte Carlo method for H3 and He4. In this paper we report the results of similar calculations for the contributions of δvTP and δvQM. These are found to be rather small.

APS and CERN Sign Open Access Agreement for SCOAP3

APS and CERN, the host organization of SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics), have signed an agreement to make the high-energy physics (HEP) articles published in three leading APS journals open access beginning January 1, 2018. This agreement acts to support the publishing of open access content for wider benefit of the HEP community.
