WebWe present a formal framework for the derivation of electroweak multipole operator from chiral effective field theory (ChEFT) charge and current operators. We explicitly derive … WebIn particular, we have discussed the recent integration of nearly-local interactions derived within chiral effective field theory, both with and without the inclusion of Δ degrees of freedom, in quantum Monte Carlo methods, namely variational Monte Carlo, Green's function Monte Carlo, and auxiliary field diffusion Monte Carlo.

Nuclear electromagnetic currents in chiral effective field theory.
WebA physical introduction to the basics of chiral dynamics is presented. Emphasis is placed on experimental tests which have generally demonstrated a strong confirmation of the … WebJun 1, 2011 · Chiral effective field theory and nuclear forces. We review how nuclear forces emerge from low-energy QCD via chiral effective field theory. The presentation is accessible to the non-specialist. At the same time, we also provide considerable detailed information (mostly in appendices) for the benefit of researchers who wish to start … WebApr 6, 2024 · We calculate the -factor for proton-proton fusion using chiral effective field theory interactions and currents. By performing order-by-order calculations with a variety of chiral interactions that are regularized and calibrated in different ways, we assess the uncertainty in the -factor from the truncation of the effective field theory ... high school math problems with answers
