Heavy hybrid stars from multi-quark interactions [PDF]

open access: yes, 2014
We explore the possibility of obtaining heavy hybrid stars within the framework of the two flavor Nambu--Jona-Lasinio model with 8-quark interactions in the scalar and in the vector channel.

Several Effects Unexplained by QCD

open access: yesUniverse, 2018
Several new experimental discoveries in high energy proton interactions, yet unexplained by QCD, are discussed in the paper. The increase of the cross sections with increasing energy from ISR to LHC, the correlation between it and the behavior of the ...

Top-quark physics at the CLIC electron-positron linear collider [PDF]

open access: yesJournal of High Energy Physics, 2018
The Compact Linear Collider (CLIC) is a proposed future high-luminosity linear electron-positron collider operating at three energy stages, with nominal centre-of-mass energies s\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym ...

Thermoelectric properties of the (an-)isotropic QGP in magnetic fields

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The Seebeck effect and the Nernst effect, which reflect the appearance of electric fields along x-axis and along y-axis ( $$E_{x}$$ E x and $$E_{y}$$ E y ), respectively, induced by the thermal gradient along x-axis, are studied in the QGP at an external

Measurements of the Production, Decay and Properties of the Top Quark: A Review [PDF]

open access: yes, 2012
With the full Tevatron Run II and early LHC data samples, the opportunity for furthering our understanding of the properties of the top quark has never been more promising.

Search for pair production of up-type vector-like quarks and for four-top-quark events in final states with multiple b-jets with the ATLAS detector [PDF]

open access: yesJournal of High Energy Physics, 2018
A search for pair production of up-type vector-like quarks (T ) with a significant branching ratio into a top quark and either a Standard Model Higgs boson or a Z boson is presented.

Polarization Effects In Hadron-Hadron Scatterings

open access: yesCumhuriyet Science Journal, 2018
In the case of diffraction scattering of hadrons by hadrons, a nonzeropolarization of the scattered particles arises, which is related to thelogarithmic derivative of the differential scattering cross section.Polarization changes sign in those reactions ...

Toward the determination of heavy-quark transport coefficients in quark-gluon plasma [PDF]

open access: yesPhysical Review C, 2018
Several transport models have been employed in recent years to analyze heavy-flavor meson spectra in high-energy heavy-ion collisions. Heavy-quark transport coefficients extracted from these models with their default parameters vary, however, by up to a ...

Quark scalar, axial, and pseudoscalar charges in the Schwinger-Dyson formalism [PDF]

open access: yes, 2014
We calculate the scalar, axial, and pseudoscalar charges of the quark in the Schwinger-Dyson formalism of Landau gauge QCD. It is found that the dressed quark scalar density of the valence quark is significantly enhanced against the bare quark ...

Rotating quark-gluon plasma in relativistic heavy ion collisions [PDF]

open access: yes, 2016
We study the rotational collective motion of the quark-gluon plasma in relativistic heavy-ion collisions using the widely adopted a multiphase transport (AMPT) model.
