Search for clustering of strange quarks in relativistic heavy ion collisions at the LHC
… from hadronic matter to a deconfined phase of quarks and gluons. We investigated whether flavor hierarchy in the QCD transition crossover region could lead to clustering of strangeness. The idea was supported by the enhanced production of strange carrying hadrons in heavy-ion collisions. Kaons …

An Equation of State with the Complete SU(3)f Baryon Octet for Neutron Star Mergers
… equation of state (EoS) is predicted to contain strange quarks, but it is difficult to model the strange degrees of freedom in a way that correctly predicts a maximum neutron star mass in excess of the heaviest known neutron stars, such as PSR J0740+6620 (2.08 ± 0.07 M⊙), and which correctly …

Measurements of Lambda, Lambda-bar and K-short from Pb-Pb collisions at 158 GeV per nucleon in a large acceptance experiment
… density. The predicted state features deconfined quarks and gluons as the relevant degrees of freedom instead of colour-singlet hadrons. These new degrees of freedom should lead to an enhanced production of strange quarks which has directly observable consequences on the composition of the final …

Color superconducting phase of cold dense quark matter
… matter can have unequal numbers of up, down, and strange quarks. The QCD interaction favors Cooper pairs that are antisymmetric in color and in flavor, and a crystalline color superconducting phase can occur which accommodates pairing between flavors with unequal number densities. In the …

Gapless color superconductivity
… and cold quark matter. At high enough densities, quarks interact with each other and form pairs similarly to electrons in superconductors. This phenomenon in the case of quark matter is called Color Superconductivity. Color superconducting matter must be electrically and color neutral, because …

Strangeness production in a quark-gluon plasma
… follows: Chapter 1 notes that the production of strangeness measured at CERN and Brookhaven has two possible explanations. One is that strange quarks, being relatively light, are easily produced, creating an abundance of strange particles in the experiment. On the other hand, hadron gas models …

The crystallography of three flavor quark matter
… All previous work on this subject neglected the strange quarks; we include them, with qualitative consequences. We calculate free energies for many crystal structures, and find two (based upon cubic symmetry) that have lower free energy than the gapless CFL phase over the lower density half of …

Search for and studies of Quark-Gluon Plasma via dynamics and productions of heavy quarks in proton-proton and heavy ion collisions at the LHC with CMS detector
Heavy flavor quarks are sensitive to both the initial stage conditions and the subsequent in-medium evolution of nuclear collisions, and thus can provide insights to the inner workings of Quark-Gluon Plasma (QGP) in large ion collisions and the origin of the collectivity in small systems. In this …

The scattering of spinning hadrons from lattice QCD
… point where the up, down and strange quarks are mass degenerate. Finite-volume spectra are calculated and, utilising the relationship between the discrete energy spectrum and the infinite-volume scattering amplitudes, partial-wave amplitudes with $J \le 3$ and the degree of …
