Phases of hadron-quark matter in (Proto) neutron stars
(Molecular Diversity Preservation International, 2019-07)
In the first part of this paper, we investigate the possible existence of a structured hadron-quark mixed phase in the cores of neutron stars. This phase, referred to as the hadron-quark pasta phase, consists of spherical ...
Heavy quark collisional energy loss in the quark-gluon plasma including finite relaxation time
(American Physical Society, 2014-07)
In this paper, we calculate the soft-collisional energy loss of heavy quarks traversing the viscous quarkgluon plasma including the effects of a finite relaxation time τπ on the energy loss. We find that the collisional ...
Quark matter and meson properties in a Nonlocal SU(3) chiral quark model at finite temperature
(SP MAIK Nauka/Interperiodica, 2012-06)
We study the finite temperature behavior of light scalar and pseudoscalar meson properties in the context of a three-flavor nonlocal chiral quark model. The model includes mixing with active strangeness degrees of freedom, ...
Neutrino emissivity in the quark-hadron mixed phase
(MDPI Multidisciplinary Digital Publishing Institute, 2018-05)
In this work we investigate the effect a crystalline quark-hadron mixed phase can have on the neutrino emissivity from the cores of neutron stars. To this end we use relativistic mean-field equations of state to model ...
Role of heavy quarks in light hadron fragmentation
(American Physical Society, 2016-08)
We investigate the role of heavy quarks in the production of light flavored hadrons and in the determination of the corresponding nonperturbative hadronization probabilities. We define a general mass variable flavor number ...
1/Nc expansion and the spin-flavor structure of the quark interaction in the constituent quark model
(American Physical Society, 2010-12)
We study the hierarchy of the coefficients in the 1/Nc expansion for the negative parity L=1 excited baryons from the perspective of the constituent quark model. This is related to the problem of determining the spin-flavor ...
Quark matter in neutron stars
(Springer, 2020)
The nonlocal three-flavor Nambu-Jona-Lasinio model is used to study quark deconfinement in the cores of neutron stars (NSs). The quark-hadron phase transition is modeled using both the Maxwell construction and the Gibbs ...
Quark deconfinement in high-mass neutron stars
(American Physical Society, 2014-01)
In this paper, we explore whether or not quark deconfinement may occur in high-mass neutron stars such as J1614 - 2230 (1.97±0.04M) and J0348 + 0432 (2.01±0.04M). Our study is based on a nonlocal extension of the SU(3) ...
Neutrino emissivity in the color superconducting quark‐hadron‐mixed phase
(John Wiley & Sons Inc, 2019)
The tremendously high pressures that exist in the cores of neutron stars may break up neutrons, protons plus other hadronic particles into their quark constituents. This transition from hadronic matter to quark matter could ...
Surface tension of hot and dense quark matter under strong magnetic fields
(American Physical Society, 2019-03)
We study the surface tension of hot, highly magnetized three-flavor quark matter droplets, focusing specifically on the thermodynamic conditions prevailing in neutron stars, hot lepton-rich protoneutron stars, and neutron ...
