Physics World, 2000 MOST physicists and astronomers believe that space, time and all the matter and radiation in the universe was formed during the big bang some 15 billion years ago. A key challenge in physics and astronomy – perhaps the ultimate challenge – is to understand how the universe we live in today evolved from the cosmic fireball created in the big bang As our

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.

Mass-radius relation for magnetized strange quark stars [PDF]
, 2010 We review the stability of magnetized strange quark matter (MSQM) within the phenomenological MIT bag model, taking into account the variation of the relevant input parameters, namely, the strange quark mass, baryon density, magnetic field and bag ...

Spin and Flavor Strange Quark Content of the Nucleon [PDF]
Phys.Rev.D78:014001,2008, 2008 Several spin and flavor dependent parameters characterizing the strangeness content of the nucleon have been calculated in the chiral constituent quark model with configuration mixing (\chiCQM_{config}) which is known to provide a satisfactory explanation of the ``proton spin crisis'' and related issues.

Strange Quark Stars — A Review [PDF]
Symposium - International Astronomical Union, 2003 A pedagogical overview of strange quark matter and strange stars is presented. After a historical notation of the research and an introduction to quark matter, a major part is devoted to the physics and astrophysics of strange stars, with attention being paid to the possible ways by which neutron stars and strange stars can be distinguished in ...

On the estimation of the strange quark mass from the experimental data on the light baryon octet
Âderna Fìzika ta Energetika, 2018 Simple relations connecting the strange quark mass to the splittings of the light hyperon masses were obtained on the basis of the phenomenological quark model compatible with the present-day theory of strong interactions, i.e.

Meissner masses in the gCFL phase of QCD [PDF]
, 2005 We calculate the Meissner masses of gluons in neutral three-flavor color superconducting matter for finite strange quark mass. In the CFL phase the eissner masses are slowly varying function of the strange quark mass. For large strange quark mass, in the

Strange Quark Matter in Stars: A General Overview [PDF]
J.Phys. G31 (2005) S651-S658, 2004 The physics of strange quark matter in the core of compact stars and recent compact star data is reviewed. Emphasis is put on the possible existence of a third family of strange quark stars.

Strange Exotic States and Compact Stars [PDF]
, 2006 We discuss the possible appearance of strange exotic multi-quark states in the interior of neutron stars and signals for the existence of strange quark matter in the core of compact stars.
