A new window on Strange Quark Matter as the ground state of strongly interacting matter
arXiv:hep-ph/0309063 · doi:10.1103/PhysRevD.69.074001
Abstract
If strange quark matter is the true ground state of matter, it must have lower energy than nuclear matter. Simultaneously, two-flavour quark matter must have higher energy than nuclear matter, for otherwise the latter would convert to the former. We show, using an effective chiral lagrangian, that the existence of a new lower energy ground state for two-flavour quark matter, the pion condensate, shrinks the window for strange quark matter to be the ground state of matter and sets new limits on the current strange quark mass.
