<title>XXI Mexican School on Particles and Fields 2026</title>
<description>&lt;p style="text-align:justify"&gt;The &lt;strong&gt;XXI Mexican School on Particles and Fields&lt;/strong&gt; takes place from &lt;strong&gt;October 19th to 23rd, 2026&lt;/strong&gt;, in the city of Puebla, Puebla, M&amp;eacute;xico. The format of the school is&amp;nbsp;such that the morning sessions are devoted to theoretical and experimental reviews, whereas parallel thematic sessions shall be held in the afternoons. All the reviews and seminars are delivered by experts of international prestige on subjects which are of current interest to the global scientific community and are also actively pursued within M&amp;eacute;xico. ​&lt;/p&gt;

&lt;p style="text-align:justify"&gt;In order to equip graduate students and attending postdocs with the necessary tools to perform fully in the school, courses of interest are taught, with English being the language of instruction. An informal and friendly atmosphere is encouraged during the courses so that the students can overcome their inhibitions and actively participate in the discussions. ​&lt;/p&gt;

&lt;p style="text-align:justify"&gt;&lt;em&gt;&lt;u&gt;&lt;strong&gt;Organizing Committee&lt;/strong&gt;&lt;/u&gt;&lt;/em&gt;&lt;/p&gt;

 <abstract>We conduct a data-driven analysis of softened hadron production in pp and AA collisions at LHC energies, using the string fragmentation model as the baseline for charged-particle production. We observed that the pT spectrum data reported by the ALICE collaboration deviate from the produced particles modeled by the fragmentation of color strings, behaving as a pT-exponential in the range between 1 and 6 GeV (intermediate pT region). This insight shows that the pT spectrum contains information on charged-particle production from two sources: fragmentation of color strings and collective phenomena that redistribute transverse momentum and enhance particle production at intermediate pT. We found scaling laws for the contribution of the softened hadrons to the pT spectrum, multiplicity and average pT, showing that the physical mechanisms producing softened hadrons have similar origins for all colliding systems, revealing a stronger dependence on freeze-out parameters than on system size.</abstract>
