Modification of jet substructure in heavy ion collisions as a probe of the resolution length of quark-gluon plasma [PDF]
Journal of High Energy Physics, 2019 We present an analysis of the role that the quark-gluon plasma (QGP) resolution length, the minimal distance by which two nearby colored charges in a jet must be separated such that they engage with the plasma independently, plays in understanding the ...

Von Wasserstoff bis Eisen, Nickel und Zink
Physik in unserer Zeit, Volume 53, Issue 4, Page 182-189, July 2022., 2022 Woraus besteht die Welt? Die Philosophen der Antike postulierten vier oder fünf Elemente. In der Neuzeit erweiterten Dimitri Mendelejew und Lothar Meyer dies auf eine rasch wachsende Tabelle der chemischen Elemente. Kirchhoff und Bunsen entdeckten Fraunhofer‐Linien im Sonnenspektrum, denen zufolge die auf der Erde existierenden Elemente auch in Sternen

Relaxation time for quark spin and thermal vorticity alignment in heavy-ion collisions
Physics Letters B, 2020 We compute the relaxation time for quark/antiquark spin and thermal vorticity alignment in a quark-gluon plasma at finite temperature and quark chemical potential.

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

Dissipative phenomena in chemically non-equilibrated quark gluon plasma [PDF]
, 1999 The dissipative corrections to the hydrodynamic equations describing the evolution of energy-momentum tensor and parton densities are derived in a simple way using the scaling approximation for the expanding quark gluon plasma at finite baryon density ...

Universal quark to gluon ratio in medium-induced parton cascade
Journal of High Energy Physics, 2018 We investigate the radiative break-up of a highly energetic quark or gluon in a high-temperature QCD plasma. Within an inertial range of momenta T ≪ ω ≪ E, where E denotes the energy of the original hard parton (jet) and T the temperature of the medium ...

Quantum Brownian motion of a heavy quark pair in the quark-gluon plasma [PDF]
Physical Review D, 2019 In this paper we study the real-time evolution of heavy quarkonium in the quark-gluon plasma (QGP) on the basis of the open quantum systems approach. In particular, we shed light on how quantum dissipation affects the dynamics of the relative motion of ...

Quasiquarks in two stream system [PDF]
, 2001 We study the collective quark excitations in an extremely anisotropic system of two interpenetrating streams of the quark-gluon plasma. In contrast to the gluon modes, all quark ones appear to be stable in such a system. Even more, the quark modes in the

Approach to equilibrium of a quarkonium in a quark-gluon plasma [PDF]
Physical Review D, 2018 We derive equations of motion for the reduced density matrix of a heavy quarkonium in contact with a quark-gluon plasma in thermal equilibrium. These equations allow in particular a proper treatment of the regime when the temperature of the plasma is ...
