matter and its stability
J. Hrtánková, M. Schäfer, J. Mareš +3
We performed calculations of nuclear systems composed solely of hyperons, aiming at exploring the possibility of existence of absolutely stable matter. We considered $Λ…
Multi-fermion systems with contact theories
Martin Schäfer, Lorenzo Contessi, Johannes Kirscher +1
We address the question of minimal requirements for the existence of quantum bound states. In particular, we demonstrate that a few-body system with zero-range momentum-independent…
On the Stability of Matter
J. Hrtánková, N. Barnea, E. Friedman +3
A hypothesis of absolutely stable strange hadronic matter composed of baryons, here denoted , is tested within many-body calculations performed using the Relativisti…
-matter: stable or unstable?
Jaroslava Hrtánková, Nir Barnea, Eliahu Friedman +3
A recent suggestion [PLB 774 (2017) 522] that purely- nuclei provide the absolute minimum energy in charge-neutral baryon matter for baryon-number , is…
