$S$-wave kaon-nucleon interactions from lattice QCD at the physical point
hep-lat 2025-08 conditional novelty 6.0 of 10

First physical-point lattice QCD calculation of S-wave kaon-nucleon interactions finds no resonance or bound state, with scattering lengths -0.226(5) fm (I=1) and +0.031(62) fm (I=0).
