Challenging chiral EFT with tritium beta decay
D. F. Ramirez Jimenez, S. Heihoff, J. Golak +6
We present a detailed investigation of tritium beta decay up to third order (N2LO) in chiral effective field theory (EFT) using the LENPIC interactions. Unlike existing studies, we…
Field-theoretical description of the deuteron breakup in the clothed particle representation
O. Shebeko, A. Arslanaliev, Y. Kostylenko +8
We present a field-theoretical description of the deuteron electrodisintegration reaction d(e,e'p)n induced by unpolarized and polarized electrons. The approach combines the Lehman…
Comparison of Relativistic and Non-relativistic Faddeev calculations for Proton-Deuteron Elastic Scattering
H. Kamada, A. Arslanaliev, Y. Kostylenko +11
This investigation compares non-relativistic and relativistic nucleon-nucleon potentials in the context of proton-deuteron scattering. Conventional NN potentials (e.g., CDBonn, AV1…
Estimating theoretical uncertainties of the two-nucleon observables by using backpropagation
K. Topolnicki, R. SkibiÅski, J. Golak
We present a novel approach to calculating theoretical uncertainties in few-nucleon calculations, making use of automatic differentiation via backpropagation, which is particularly…
