Two loop vertices and tree level multicollinear limits in QCD [PDF]

open access: yes, 2005
We present a summary of the methods required to solve loop-integrals and their reduction to Master Integrals. We then present the expansion in d = 4 - 2e of the Master Integrals required for the two loop massless vertex diagrams with three off-shell legs.

Recent hard probe measurements from STAR

open access: yesEPJ Web of Conferences, 2017
High momentum transfer processes can be reliably calculated by perturbative quantum chromodynamics (pQCD). Products of those hard processes, high transverse momentum particles, jets, and heavy quarks (hard probes), interact with the quark-gluon plasma ...

On Extracting Thermal Parameters and Scenario in High‐Energy Collisions

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
The inconsistent thermal parameters derived from various models in high‐energy collisions are examined. A comprehensive literature review suggests model‐independent parameters to address these inconsistencies, based on the average transverse momentum 〈pT〉 and root‐mean‐square transverse momentum pT2.

Direkte Photonen in Schwerionenkollisionen [PDF]

open access: yes, 2011
Direct photon emission from heavy-ion collisions has been calculated and compared to available experimental data. Three different models have been combined to extract direct photons from different environments in a heavy-ion collision: Thermal photons ...

Bayesian inference and jet quenching [PDF]

open access: yesEPJ Web of Conferences
These proceedings review the application of Bayesian inference to high momentum transfer probes of the quark–gluon plasma (QGP). Bayesian inference techniques are introduced, highlighting critical components to consider when comparing analyses.

Revealing the Harmonic Structure of Nuclear Two-Body Correlations in High-Energy Heavy-Ion Collisions. [PDF]

open access: yesPhysical Review Letters
Smashing nuclei at ultrarelativistic speeds and analyzing the momentum distribution of outgoing debris provides a powerful method to probe the many-body properties of the incoming nuclear ground states.

On the Square Speed of Sound in High‐Energy Collisions: Range of Values and How to Understand It

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
After reviewing the sound speeds in various forms and conditions of matter, we investigate the sound speed of hadronic matter that has decoupled from the hot and dense system formed during high‐energy collisions. We comprehensively consider factors such as energy loss of the incident beam, rapidity shift of leading nucleons, and the Landau hydrodynamic

Holographic Duals of Symmetry Broken Phases

open access: yesFortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract A novel interpretation of Symmetry Topological Field Theories (SymTFTs) as theories of gravity is explored by proposing a holographic duality where the bulk SymTFT (with the gauging of a suitable Lagrangian algebra) is dual to the universal effective field theory (EFT) that describes spontaneous symmetry breaking on the boundary.

Transverse structure of the proton beyond leading twist: A light-front Hamiltonian approach

open access: yesPhysics Letters B
Within the Basis Light-Front Quantization framework, we systematically investigate the subleading twist (twist-3) transverse-momentum-dependent parton distribution functions (TMDs) of the proton beyond the Wandzura-Wilczek (WW) approximation.
