Thermodynamics, strange quark matter, and strange stars [PDF]

Physical Review C, 2000
Because of the mass density-dependence, an extra term should be added to the expression of pressure. However, it should not appear in that of energy according to both the general ensemble theory and basic thermodynamic principle.

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 ...

Strangelets and Strange Quark Matter [PDF]

Nucl.Phys. A639 (1998) 443-450, 1997
The properties of finite lumps of strange quark matter (strangelets) with emphasis on the two scenarios of producing strange matter in relativistic heavy ion collisions are summarized. As an outlook, the possibility of short-lived strange composites and charmed matter are discussed for coming heavy ion experiments.

Strange Quark Matter Theory [PDF]

Journal of Physics G: Nuclear and Particle Physics, 2003
Theoretical approaches to strange and other types of quark matter accounted for at the SQM2003 Meeting are reviewed. They range from simple statistical models through perturbative QCD supported mico-dynamical simulations til lattice gauge theory and ...

Properties of strange quark matter and strange quark stars

European Physical Journal C: Particles and Fields, 2021
A Polyakov chiral $$\text {SU(3)}$$ SU(3) quark mean-field (PCQMF) model is applied to study the properties of strange quark matter (SQM) and strange quark star (SQS) in $$\beta $$ β -equilibrium.

Strange quark matter in a chiral SU(3) quark mean field model [PDF]

Phys.Rev. C67 (2003) 015210, 2002
We apply the chiral SU(3) quark mean field model to investigate strange quark matter. The stability of strange quark matter with different strangeness fraction is studied. The interaction between quarks and vector mesons destabilizes the strange quark matter.

Strange hadronic matter

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.

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 ...

A new window on Strange Quark Matter as the ground state of strongly interacting matter [PDF]

Phys.Rev. D69 (2004) 074001, 2003
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 ...

Solitonic effect on relativistic string cloud spacetime attached with strange quark matter

AIMS Mathematics
In this research paper, we discussed some geometric axioms of a relativistic string cloud spacetime attached with strange quark matter. We determined the conformal $ \eta $-Ricci soliton on a relativistic string cloud spacetime attached with strange ...
