Exploring the spin structure of the nucleon at STAR [PDF]

open access: yesEPJ Web of Conferences
Understanding the internal spin structure of the nucleon remains a challenge in strong interaction physics. The unique capability of RHIC opened new avenues in studying the internal structure of the proton with unprecedented depth and precision ...

Heavy Quarkonium States With Baryonic Chemical Potential

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential. The binding energies of the quarkonium states has been obtained by using quasiparticle Debye mass which further depends on temperature and baryonic chemical potential (μb ...

The Search for Higher Twist Effects in the Spin-Structure Functions of the Neutron

open access: yes, 2020
. Jefferson Lab experiment E97-103 measured the spin structure function g n 2 from a Q 2 of 0.58 to 1.36 with a nearly constant x of 0.2. Combining this data with a fit to the world g n 1 data, the size of higher twist contributions to g n 2 can be ...

Studying the hadron structure with PANDA and CLAS using machine learning techniques

open access: yes, 2023
The hadron spectroscopy and structure are currently very active fields of research to study the non-perturbative regime of quantum chronodynamics. The first one studies the complex structure of excited hadrons by looking at their decay products, while ...

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.

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.

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

Probing the Short-Distance Structure of the Quark-Gluon Plasma with Energy Correlators

open access: yesPhysical Review Letters
Energy-energy correlators (EECs) are promising observables to study the dynamics of jet evolution in the quark-gluon plasma (QGP) through its imprint on angular scales in the energy flux of final-state particles. We carry out the first complete calculation of EECs using realistic simulations of high-energy heavy-ion collisions and dissect the different

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.
