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.

Nonperturbative strange-quark sea from lattice QCD, light-front holography, and meson-baryon fluctuation models [PDF]
Physical Review D, 2018 We demonstrate that a nonzero strangeness contribution to the spacelike electromagnetic form factor of the nucleon is evidence for a strange-antistrange asymmetry in the nucleon's light-front wave function, thus implying different nonperturbative ...

Analysis of the pseudoscalar hidden-charm tetraquark states with the QCD sum rules
Nuclear Physics B, 2022 In this work, we take all the color-antitriplet diquarks, such as the scalar, pseudoscalar, vector, axialvector and tensor diquarks, as the basic constituents to construct the local pseudoscalar four-quark currents without importing the explicit P-waves ...

Strangeness counting in high energy collisions [PDF]
, 1998 The estimates of overall strange quark production in high energy e+e-, pp and ppbar collisions by using the statistical-thermal model of hadronisation are presented and compared with previous works.

FLRW cosmological models with quark and strange quark matters in f(R,T)$f(R,T)$ gravity [PDF]
, 2018 In this paper, we have studied the magnetized quark matter (QM) and strange quark matter (SQM) distributions in the presence of f(R,T)$f(R,T)$ gravity in the background of Friedmann-Lemaître-Robertson-Walker (FLRW) metric.

Relativistic strange quark stars in Lovelock gravity [PDF]
The European Physical Journal Plus, 2019 We study relativistic non-rotating stars in the framework of Lovelock gravity. In particular, we consider the Gauss-Bonnet term in a five-dimensional spacetime, and we investigate the impact of the Gauss-Bonnet parameter on properties of the stars, both ...

Quark, pion and axial condensates in three-flavor finite isospin chiral perturbation theory
European Physical Journal C: Particles and Fields, 2021 We calculate the light-quark condensate, the strange-quark condensate, the pion condensate, and the axial condensate in three-flavor chiral perturbation theory ( $$\chi $$ χ PT) in the presence of an isospin chemical potential at next-to-leading order at

On the estimation of the strange quark mass from the experimental data on the light baryon octet
Ядерна фізика та енергетика, 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.

Thermal Evolution and Light Curves of Young Bare Strange Stars [PDF]
, 2002 The cooling of a young bare strange star is studied numerically by solving the equations of energy conservation and heat transport for both normal and superconducting strange quark matter inside the star.

Dark matter admixed strange quark stars in the Starobinsky model [PDF]
, 2018 We compute the mass-to-radius profiles for dark matter admixed strange quark stars in the Starobinsky model of modified gravity. For quark matter we assume the MIT bag model, while self-interacting dark matter inside the star is modelled as a Bose ...
