Abstract
This Low Energy Nuclear Physics International Collaboration (LENPIC) paper provides an example of $a\phantom{\rule{0}{0ex}}b$-$i\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}o$ nuclear structure calculations worth noting. Using chiral effective field theory starting from two-body and three-body nuclear data, the authors work up through $p$-shell nuclei, with careful attention paid to quantifying the theoretical uncertainties. The remaining discrepancies with experiment, particularly overbinding in the upper $p$ shell, point to next steps to be taken. As a caveat, known excited states that cannot be well described within current computational limitations are missing.
