Probing the shape of the quark-gluon plasma droplet via event-by-event quark-gluon plasma tomography

This study investigates quark-gluon plasma in heavy-ion collisions through two avenues: high-<a:math xmlns:a="http://www.w3.org/1998/Math/MathML"><a:msub><a:mi>p</a:mi><a:mo>⊥</a:mo></a:msub></a:math> frameworks and hydrodynamic modeling. Using the <b:math xmlns:b="http://www.w3.org/1998/Math/MathML"><b:mrow><b:msub><b:mi mathvariant="normal">T</b:mi><b:mtext>R</b:mtext></b:msub><b:mi>ENTo</b:mi></b:mrow></b:math> model, we find that the <d:math xmlns:d="http://www.w3.org/1998/Math/MathML"><d:mrow><d:mi>p</d:mi><d:mo>=</d:mo><d:mn>0</d:mn></d:mrow></d:math> value aligns well with high-<e:math xmlns:e="http://www.w3.org/1998/Math/MathML"><e:msub><e:mi>p</e:mi><e:mo>⊥</e:mo></e:msub></e:math> data, in agreement with Bayesian analysis of the low-<f:math xmlns:f="http://www.w3.org/1998/Math/MathML"><f:msub><f:mi>p</f:mi><f:mo>⊥</f:mo></f:msub></f:math> regime. While adjusting <g:math xmlns:g="http://www.w3.org/1998/Math/MathML"><g:mi>p</g:mi></g:math> values may improve a fit to a particular high-<h:math xmlns:h="http://www.w3.org/1998/Math/MathML"><h:msub><h:mi>p</h:mi><h:mo>⊥</h:mo></h:msub></h:math> observable, it does not permit an earlier onset of transverse expansion.
