Recovering the Conformal Limit of Color Superconducting Quark Matter within a Confining Density Functional Approach [PDF]

open access: greenParticles, 2022
We generalize a recently proposed confining relativistic density-functional approach to the case of density-dependent vector and diquark couplings. The particular behavior of these couplings is motivated by the non-perturbative gluon exchange in dense ...

Six flavor quark matter [PDF]

open access: yesJournal of High Energy Physics, 2018
Macroscopic nuggets of quark matter were proposed several decades ago as a candidate for dark matter. The formation of these objects in the early universe requires the QCD phase transition to be first order — a requirement that is not satisfied in the ...

Quark matter and quark stars at finite temperature in Nambu–Jona-Lasinio model

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We extend the SU(3) Nambu–Jona-Lasinio (NJL) model to include two types of vector interaction. Using these two types of vector interaction in NJL model, we study the quark symmetry free energy in asymmetric quark matter, the constituent quark mass, the ...

Search for dark matter produced in association with a single top quark or a top quark pair in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV [PDF]

open access: diamondJournal of High Energy Physics, 2019
A search for dark matter produced in association with top quarks in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The data set used corresponds to an integrated luminosity of 35.9 fb−1 recorded with the CMS detector at the ...

Effects of quark-matter symmetry energy on hadron-quark coexistence in neutron-star matter [PDF]

open access: greenPhysical Review C, 2018
We examine the effects of the isovector-vector coupling and hypercharge-vector coupling in quark matter on hadron-quark coexistence in neutron-star matter.

Strongly interacting matter exhibits deconfined behavior in massive neutron stars [PDF]

open access: yesNature Communications, 2023
Neutron-star cores contain matter at the highest densities in our Universe. This highly compressed matter may undergo a phase transition where nuclear matter melts into deconfined quark matter, liberating its constituent quarks and gluons.

Gravitational Wave Signal for Quark Matter with Realistic Phase Transition. [PDF]

open access: yesPhysical Review Letters, 2022
The cores of neutron stars (NSs) near the maximum mass can realize a transitional change to quark matter (QM). Gravitational waves from binary NS mergers are expected to convey information about the equation of state (EOS) sensitive to the QM transition.

Soft Interactions in Cold Quark Matter. [PDF]

open access: yesPhysical Review Letters, 2021
Accurate knowledge of the thermodynamic properties of zero-temperature, high-density quark matter plays an integral role in attempts to constrain the behavior of the dense QCD matter found inside neutron-star cores, irrespective of the phase realized ...

Stiffening of matter in quark-hadron continuity [PDF]

open access: yesPhysical Review D, 2021
We discuss stiffening of matter in quark-hadron continuity. We introduce a model that relates quark wave functions in a baryon and the occupation probability of states for baryons and quarks in dense matter.
