Medium modification of strange hadronic resonances at SIS, RHIC and LHC energies [PDF]

EPJ Web of Conferences, 2018
The properties of strange pseudoscalar and vectors mesons as well as strange baryon resonances in dense matter are reviewed. Some open questions on the properties of strange hadrons in medium are addressed, such as the experimental signatures of inmedium

Impact of dark matter on strange quark stars described by different quark models [PDF]

European Physical Journal C: Particles and Fields
Dark matter is hypothesized to interact with ordinary matter solely through gravity and may be present in compact objects such as strange quark stars. We treat strange quark stars admixed with dark matter as two-fluid systems to investigate the potential

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 ...

Behaviour of Quark and Strange Quark Matter for Higher Dimensional Bianchi Type -I Universe in f(R,T) Gravity

East European Journal of Physics
This research paper delves into a thorough examination of the behaviour exhibited by higher dimensional Bianchi Type-I universes, incorporating the presence of quark and strange quark matter within the framework of f(R,T) gravity.

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

Strange hadronic matter [PDF]

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.

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.

Confronting Strange Stars with Compact-Star Observations and New Physics

Universe, 2023
Strange stars ought to exist in the universe according to the strange quark matter hypothesis, which states that matter made of roughly equal numbers of up, down, and strange quarks could be the true ground state of baryonic matter rather than ordinary ...

Gravitational Waves from Strange Star Core–Crust Oscillation

Universe, 2022
According to the strange quark matter hypothesis, pulsars may actually be strange stars composed of self-bound strange quark matter. The normal matter crust of a strange star, unlike that of a normal neutron star, is supported by a strong electric field.

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.
