Phase transition from nuclear matter to color superconducting quark matter

, 2003
We construct the nuclear and quark matter equations of state at zero temperature in an effective quark theory (the Nambu-Jona-Lasinio model), and discuss the phase transition between them.

Strange Quark Matter and Strange Quark Stars

, 2016
New forms of matter such as super-hypernuclei(strange quark matter) and superhypernuclear stars(strange quark stars) are discussed in some detail, based on the so-called “Bodmer–Terazawa–Witten hypothesis” assuming that they are stable or quasi ...

Effects of axion interactions on quark stars in 4D Einstein–Gauss–Bonnet gravity

European Physical Journal C: Particles and Fields
We explore the properties of quark stars by combining the microscopic axion-extended Polyakov–Nambu–Jona-Lasinio model with the macroscopic framework of four-dimensional Einstein–Gauss–Bonnet (4D EGB) gravity. Specifically, axion effects are incorporated

Twist-2 relations for the twist-3 tensor-polarized distribution function fLT of a spin-1 hadron by the operator-product-expansion method

Physics Letters B
In a spin-1 hadron, tensor-polarized parton distribution functions (PDFs) exist. The twist-2 function is f1LL and a twist-3 one is fLT. Because an experiment is under preparation at the Thomas Jefferson National Accelerator Facility (JLab) to measure the

Tensor-polarized twist-3 parton distribution functions fLT(x) for the spin-1 deuteron by using twist-2 relations

Physics Letters B
Tensor-polarized twist-3 parton distribution functions (PDFs) fLT(x) are calculated for the spin-1 deuteron by using twist-2 relations, which are similar to the Wandzura-Wilczek relation and the Burkhardt-Cottingham sum rule in the spin-1/2 nucleon ...

Two–fluid CFL strange quark stars with scalar dark matter: Critical mass and mass–gap implications

Nuclear Physics B
We investigate the structure of strange quark stars (SQSs) in the color–flavor–locked (CFL) phase in the presence of scalar bosonic dark matter within a two–fluid formalism.

Strange Quark Matter as Dark Matter

, 2019
New forms of matter such as super-hypernuclei (strange quark matter) and superhypernuclear stars (strange quark stars) as candidates for dark matter are discussed in some detail, based on the so-called “Bodmer–Terazawa–Witten hypothesis” assuming that ...

Strongly interacting quark matter in massive quark stars

Classical and Quantum Gravity
Abstract This paper investigates the properties of strongly coupled matter at high baryon densities (ρ B) in quark stars (QSs). The QS model is based on the density-dependent quark mass (DDQM) framework, modified DDQM (MDDQM) by enhancing the single-gluon interaction to generate higher repulsive pressure.
