Quark star matter at finite temperature in a quasiparticle model

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We study the thermodynamic properties of asymmetric quark matter, large mass quark stars (QSs), and proto-quark stars (PQSs) within the quasiparticle model. Considering the effects of temperature within quasiparticle model can significantly influence the

Hybrid stars with large strange quark cores [PDF]

open access: yesEPJ Web of Conferences, 2022
The possible existence of hybrid stars is studied using several multiquark interaction channels. The hadronic phase consists of an equation of state (EoS) with presently accepted nuclear matter properties and the quark model is constrained by the vacuum ...

QUARK MATTER SYMMETRY ENERGY AND QUARK STARS [PDF]

open access: yesThe Astrophysical Journal, 2013
We extend the confined-density-dependent-mass (CDDM) model to include isospin dependence of the equivalent quark mass. Within the confined-isospin-density-dependent-mass (CIDDM) model, we study the quark matter symmetry energy, the stability of strange quark matter, and the properties of quark stars.

Properties of strange quark matter and strange quark stars

open access: yesEuropean 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.

Dense hadron star in quark degree of freedom

open access: yesEPJ Web of Conferences, 2014
The quark degree of freedom may play an important role as one studies dense hadron stars which can help to understand the universe origin. We add a temperature dependence to the effective quark mass adopted from a quark-quark interaction on the QCD basis

Search for top quark decays t → qH with H → γγ using the ATLAS detector [PDF]

open access: yes, 2014
A search is performed for flavour-changing neutral currents in the decay of a top quark to an up-type (c, u) quark and a Higgs boson, where the Higgs boson decays to two photons.

The Hadron-quark Crossover in Neutron Star within Gaussian Process Regression Method

open access: yesThe Astrophysical Journal, 2022
The equations of state of the neutron star at the hadron-quark crossover region are interpolated with the Gaussian process regression (GPR) method, which can reduce the randomness of present interpolation schemes.
