Systematic Nuclear Uncertainties in the Hypertriton System

The hypertriton bound state is relevant for inference of knowledge about the hyperon-nucleon (YN) interaction. In this work we compute binding energy using ab initio hypernuclear no-core shell model (NCSM) with realistic interactions derived from chiral effective field theory. particular, employ a large family nucleon-nucleon aim to quantify theoretical precision predicted observables arising nuclear-physics uncertainties. three-body calculations are performed in relative Jacobi-coordinate harmonic oscillator basis and implement infrared correction formulas extrapolate NCSM results infinite space. We find that spread energy, attributed nuclear-interaction uncertainty, 100 keV. conclusion, sensitivity uncertainties same order magnitude as experimental such bound-state observable can be used calibration procedure constrain YN interactions.
