Properties of strange quark matter and strange quark stars [PDF]

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.

Searching for strange quark matter objects among white dwarfs

Physics Letters B, 2022
The ground state of matter may be strange quark matter (SQM), not hadronic matter. A whole sequence of SQM objects, ranging from strange quark stars and strange quark dwarfs to strange quark planets, can stably exist according to this SQM hypothesis.

Repeating fast radio bursts from collapses of the crust of a strange star [PDF]

The Innovation, 2021
Summary: Strange stars (SSs) are compact objects made of deconfined quarks. It is hard to distinguish SSs from neutron stars as a thin crust composed of normal hadronic matter may exist and obscure the whole surface of the SS.

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 ...

Boiling of strange-quark matter [PDF]

Physical Review D, 1991
Boiling of strange-quark matter is studied assuming baryon chemical equilibrium between a quark phase described by the bag model, and a hadron phase described by Walecka's mean-field theory. Boiling of quark nuggets at high temperatures is shown to be much less efficient than previously believed. Thus quark nuggets with large baryon numbers may survive

Search for Charged Strange Quark Matter Produced in11.5AGeV/cAu+PbCollisions [PDF]

AIP Conference Proceedings, 1997
We present the results of a search for strange quark matter from central 11.6 A GeV/c Au+Pb collisions in experiment E864 at the BNL-AGS. Nearly 6 billion central interactions have been sampled during the 1995 run search for positively and negatively charged, as well as neutral strangelets. The search was conducted with a high mass trigger system.

Influence of dark matter on the structure of strange quark stars in one-fluid model [PDF]

European Physical Journal C: Particles and Fields
This work studies the influence of scalar dark matter on the structural properties of strange quark stars (SQS) within a one-fluid framework, considering Yukawa interactions between dark matter and quark matter.

Search for Strange Quark Matter and Nuclearites on Board the International Space Station (SQM-ISS): A Future Detector to Search for Massive, Non-Relativistic Objects in Space [PDF]

Sensors
SQM-ISS is a detector that will search from the International Space Station for massive particles possibly present among the cosmic rays. Among them, we mention strange quark matter, Q-Balls, lumps of fermionic exotic compact stars, Primordial Black ...

Dark Matter, Neutron Stars, and Strange Quark Matter [PDF]

Physical Review Letters, 2010
We show that self-annihilating neutralino WIMP dark matter accreted onto neutron stars may provide a mechanism to seed compact objects with long-lived lumps of strange quark matter, or strangelets, for WIMP masses above a few GeV. This effect may trigger a conversion of most of the star into a strange star.

Looking for Strange Quark Matter in Cosmic Rays.

EPJ Web of Conferences, 2013
Usually it is supposed that the definition of the CR mass composition in knee region is the key to problem of CR spectrum modification in this range. However tens of the experiments were done for the last half of century and have not decided this problem
