Strange matter in compact stars [PDF]
EPJ Web of Conferences, 2018 We discuss possible scenarios for the existence of strange matter in compact stars. The appearance of hyperons leads to a hyperon puzzle in ab-initio approaches based on effective baryon-baryon potentials but is not a severe problem in relativistic mean ...

Physical Review Letters, 1993 We have studied the composition, stability, and production mechanisms of strange hadronic matter. By applying the RMF model to systems of nucleons, Λ’s, Σ’s, and Ξ’s, stable systems with hyperon lifetimes and charge to mass ratio close to zero are obtained. In this extended model, purely hyperonic matter consisting of lambda’s and cascades is predicted.

Dynamics of Strangeness Production and Strange Matter Formation
, 1996 The dynamics of a hadronizing quark matter drop is investigated with a hybrid-like model, which takes into account equilibrium as well as non-equilibrium features of the process. We study the the particle rates from the hadronizing plasma, which have to be put in relation to the whole time evolution of the system.

Strangeness in stellar matter [PDF]
Acta Physica Hungarica A) Heavy Ion Physics, 1996 A protoneutron star is formed immediately after the gravitational collapse of the core of a massive star. At birth, the hot and high density matter in such a star contains a large number of neutrinos trapped during collapse. Trapped neutrinos generally inhibit the presence of exotic matter -- hyperons, a kaon condensate, or quarks.

Strangeness and charm in nuclear matter [PDF]
Nuclear Physics A, 2013 The properties of strange ($K$, $\bar K$ and $\bar K^*$) and open-charm ($D$, $\bar D$ and $D^*$) mesons in dense matter are studied using a unitary approach in coupled channels for meson-baryon scattering. In the strangeness sector, the interaction with nucleons always comes through vector-meson exchange, which is evaluated by chiral and hidden gauge ...

Quark Matter May Not Be Strange [PDF]
Physical Review Letters, 2018 If quark matter is energetically favored over nuclear matter at zero temperature and pressure then it has long been expected to take the form of strange quark matter (SQM), with comparable amounts of $u$, $d$, $s$ quarks. The possibility of quark matter with only $u$, $d$ quarks ($ud$QM) is usually dismissed because of the observed stability of ...

Strangeness in hadronic stellar matter [PDF]
Physical Review C, 1995 We examine the presence of strangeness-bearing components, hyperons and kaons, in dense neutron star matter. Calculations are performed using relativistic mean field models, in which both the baryon-baryon and kaon-baryon interactions are mediated by meson exchange.
