Low-energy chiral two-pion exchange potential with statistical uncertainties
Low-energy chiral two-pion exchange potential with statistical uncertainties
We present a new phenomenological nucleon-nucleon $(NN)$ chiral potential fitted to $925 pp$ and $1743 np$ scattering data selected from the Granada-$2013 NN$ database up to a laboratory energy of 125 MeV with 20 short-distance parameters and three chiral constants ${c}_{1},\phantom{\rule{0.16em}{0ex}}{c}_{3}$, and ${c}_{4}$ with ${\ensuremath{\chi}}^{2}/\ensuremath{\nu}=1.02$. Special attention is given to …
