PERTURBATIVE QCD DESCRIPTION OF MULTIPARTICLE CORRELATIONS IN QUARK AND GLUON JETS [PDF]

open access: yes, 1998
The QCD evolution equations in Modified Leading Log Approximation for the factorial moments of the multiplicity distribution in quark and gluon jets are numerically solved with initial conditions at threshold by fully taking into account the energy ...

Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC‐BCS Crossover

open access: yesAdvanced Science, Volume 12, Issue 31, August 21, 2025.
This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

Phenomenological aspects of an anisotropic quark-gluon plasma [PDF]

open access: yes, 2010
In this work we investigate phenomenological aspects of an anisotropic quark-gluon plasma. In the first part of this thesis, we formulate phenomenologicalmodels that take into account the momentumspace anisotropy of the system developed during the ...

Di-hadron correlations with identified leading hadrons in 200 GeV Au+Au and d+Au collisions at STAR

open access: yesPhysics Letters B, 2015
The STAR Collaboration presents for the first time two-dimensional di-hadron correlations with identified leading hadrons in 200 GeV central Au+Au and minimum-bias d+Au collisions to explore hadronization mechanisms in the quark gluon plasma.

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures

open access: yesContributions to Plasma Physics, Volume 65, Issue 7, August 2025.
ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Ausbreitung von Jets und Entstehung von Machkegeln in (3+1) dimensionaler idealer Hydrodynamik [PDF]

open access: yes, 2009
This thesis investigates the jet-medium interactions in a Quark-Gluon Plasma using a hydrodynamical model. Such a Quark-Gluon Plasma represents a very early stage of our universe and is assumed to be created in heavy-ion collisions.

Facets of the QCD Phase-Diagram

open access: yesEPJ Web of Conferences, 2011
In this contribution we will discuss two aspects of the matter created in ultra-relativistic heavy ion collisions. First we will attempt to define a universal measure for the fluidity of a substance, which will allow a correct comparison between the ...

Heavy - light flavor correlations of anisotropic flows at LHC energies within event-by-event transport approach

open access: yesPhysics Letters B, 2020
The heavy quarks (HQs) are a unique probe of the hot QCD matter properties and their dynamics are coupled to the locally thermalized expanding quark gluon plasma.

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Signatures of quark gluon plasma formation in high-energy heavy ion collisions : a critical review [PDF]

open access: yes, 2005
Ultra-relativistic heavy ion collisions offer the unique opportunity to probe highly excited dense nuclear matter under controlled laboratory conditions. The compelling driving force for such studies is the expectation that an entirely new form of matter
