Model comparisons of transverse energy and charged-particle multiplicity in A + A collisions at midrapidity from s N N = 7.7–200 GeV

N. Magdy, Antonio Carlos Oliveira da Silva, Christal Martin, Josie Hakanson et autres

Abstract We present a comprehensive comparison of PHENIX measurements of transverse energy production (d E T /d η ) and charged-particle multiplicity (d N /d η ) at midrapidity to simulations from PYTHIA-8, AMPT, HIJING, and SMASH. These comparisons span both small …

Interplay of prompt and non-prompt photons in photon-triggered jet observables

C. Sirimanna, Y. Tachibana, Abhijit Majumder, A. Angerami et autres

Prompt photons are important yet challenging to observe in relativistic heavy-ion collisions, as they are produced in the early stages and traverse almost the entire QGP medium without interaction. Experimental analyses typically employ isolation cuts, in the hope to identify prompt photons. …

Model Comparisons of Transverse Energy and Charged-Particle Multiplicity in A+A Collisions at Midrapidity from $\sqrt{s_{NN}}$ $=$ 7.7 to 200~GeV

N. Magdy, A. Silva, Christal Martin, Josie Hakanson et autres

We present a comprehensive comparison of PHENIX measurements of transverse energy production ($dE_T/dη$) and charged-particle multiplicity ($dN/dη$) at midrapidity to simulations from PYTHIA-8, AMPT, HIJING, and SMASH. These comparisons span both small systems (d+Au, $^3$He+Au) and large systems (Cu+Cu, Cu+Au, Au+Au, and …

Hybrid Hadronization of Jet Showers from $e^++𝑒^−$ to $𝐴 + 𝐴$ with JETSCAPE

Cameron Parker, A. Angerami, R. Arora, Steffen A. Bass et autres

In this talk we review jet production in a large variety of collision systems using the JETSCAPE event generator and Hybrid Hadronization. Hybrid Hadronization combines quark recombination, applicable when distances between partons in phase space are small, and string fragmentation appropriate for …

Effects of multi-scale jet-medium interactions on jet substructures

Y. Tachibana, A. Angerami, Ritu Arora, Steffen A. Bass et autres

We utilize event-by-event Monte Carlo simulations within the JETSCAPE framework to examine scale-dependent jet-medium interactions in heavy-ion collisions. The reduction in jet-medium interaction during the early high-virtuality stage, where the medium is resolved at a short distance scale, is emphasized as a …

Multiscale evolution of heavy flavor in the QGP

G. Vujanovic, A. Angerami, Ritu Arora, Steffen A. Bass et autres

Shower development dynamics for a jet traveling through the quark-gluon plasma (QGP) is a multiscale process, where the heavy flavor mass is an important scale. During the high virtuality portion of the jet evolution in the QGP, emission of gluons from a …

A multistage framework for studying the evolution of jets and high-pT probes in small collision systems

Abhijit Majumder, A. Angerami, Ritu Arora, Steffen A. Bass et autres

Understanding the modification of jets and high-$p_T$ probes in small systems requires the integration of soft and hard physics. We present recent developments in extending the JETSCAPE framework to build an event generator, which includes correlations between soft and hard partons, to …

3D Multi-system Bayesian Calibration with Energy Conservation to Study Rapidity-dependent Dynamics of Nuclear Collisions

Andi Mankolli, A. Angerami, Ritu Arora, Steffen A. Bass et autres

Considerable information about the early-stage dynamics of heavy-ion collisions is encoded in the rapidity dependence of measurements. To leverage the large amount of experimental data, we perform a systematic analysis using three-dimensional hydrodynamic simulations of multiple collision systems -- large and small, …
