2026-10-23T16:30:00 2026-10-23T16:40:00 00:10 We study the charged particle production in ultrarelativistic collisions within the color string fragmentation picture. In this picture, we describe the $p_T$ spectrum as the convolution of the Schwinger mechanism with string tension fluctuations. Importantly, reproducing the power-law tail of the experimental $p_T$ spectrum requires heavy-tailed distributions. For instance, the recently introduced $q$-Gaussian string-tension fluctuations yield a Tricomi function that captures the low and high $p_T$ regimes. In this work, we study the power-law tail in the $p_T$ spectrum, present in several models, including the Hagedorn function, the two-component model, and the description for the softened hadron production. Interestingly, these models can be studied in the high-$p_T$ regime as Pareto-type string tension fluctuations, which are compatible with the KNO scale invariance required for describing hard processes. Additionally, the heavy-tailed string tension fluctuations are accompanied by temperature fluctuations, indicating that the medium where the particles are produced is out of equilibrium. We apply this framework to ALICE data and extract the effective temperature and the power-law trend of the high-$p_T$ particle production. The latter shows clear trends with event multiplicity and collision centrality, consistent with enhanced hard-particle production in small systems and with high-$p_T$ particle suppression in heavy ion collisions. slides doc http://indico.nucleares.unam.mx/images/word.png word file ppt http://indico.nucleares.unam.mx/images/powerpoint.png powerpoint file pdf http://indico.nucleares.unam.mx/images/pdf_small.png pdf file odt http://indico.nucleares.unam.mx/images/writer.png writer file odp http://indico.nucleares.unam.mx/images/impress.png presentation file ods http://indico.nucleares.unam.mx/images/calc.png spreadsheet file other http://indico.nucleares.unam.mx/images/file_small.png unknown type file link http://indico.nucleares.unam.mx/images/link.png link 0 doc http://indico.nucleares.unam.mx/images/word.png word file ppt http://indico.nucleares.unam.mx/images/powerpoint.png powerpoint file pdf http://indico.nucleares.unam.mx/images/pdf_small.png pdf file odt http://indico.nucleares.unam.mx/images/writer.png writer file odp http://indico.nucleares.unam.mx/images/impress.png presentation file ods http://indico.nucleares.unam.mx/images/calc.png spreadsheet file other http://indico.nucleares.unam.mx/images/file_small.png unknown type file link http://indico.nucleares.unam.mx/images/link.png link
