Emergence of ${}^4$H $J^{\pi }=1^{-}$ resonance in contact theories

Lorenzo Contessi, Martin Schäfer, Johannes Kirscher +2

We obtain the $s$- and $p$-wave low-energy scattering parameters for n${}^3$H elastic scattering and the position of the ${}^4$H $J^{\pi }=1^{-}$ resonance using the pionless effective field…
