trailUp-down quark matter may be more stable than strange quark matter
Strange quark matter is the true ground state of baryonic matter
Some observed compact stars may be strange quark stars
Flavor-dependent vacuum dynamics favors two flavors· for
Quark-meson model calculations find bulk up-down quark matter has lower energy per baryon than strange quark matter
Flavor-dependent dynamical chiral symmetry breaking energetically penalizes strange quarks in quark matter
Some NJL-model calculations find two-flavor quark matter more stable than three-flavor quark matter
atomic
Up-down quark matter stable only above baryon number about 300 is consistent with ordinary nuclear stability
No known atomic nucleus has a baryon number greater than about 300
Coulomb barriers and fission instability prevent ordinary nuclei from aggregating to baryon numbers above 300 under natural conditions
Bag-model expectation favors strangeness· against
In bag-model calculations strange quark matter has lower energy per baryon than two-flavor quark matter
atomic
assumed
First-principles QCD calculations cannot determine whether strange quark matter is stable
