W4-5 Theory I (DNP) / Théorie I (DPN)
- Jason Holt (TRIUMF)
Recent developments of the relativistic nuclear field theory (NFT) on the fermionic correlation functions will be presented. The general non-perturbative equation of motion framework is formulated in terms of a closed system of non-linear equations for one-body and two-body propagators. The present formulation provides a direct link to ab-initio theories and extends the explicit treatment of...
We present the first ab-initio calculations of the structure factors for elastic spin-dependent WIMP scattering off $^{19}$F, $^{27}$Al, $^{23}$Na, $^{27}$Al, $^{29}$Si, $^{73}$Ge, $^{127}$I and $^{129,131}$Xe. A set of established two- (NN) and three-nucleon (3N) interactions derived from chiral effective field theory (EFT) are used for nuclear interaction, including N$^3$LO-level NN +...
We apply the no-core shell model with continuum technique to investigate nuclear reactions involving p+7Li and n+7Be with 8Be as the composite system. This method enables accurate description of both bound states and the continuum using chiral nucleon-nucleon and three-nucleon forces as input. We report phase-shifts, astrophysical S-factors and cross-sections for a suite of scattering and...
