<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 determine the temperature fluctuations associated with the particle production in pp collisions through the derivation of the string tension distribution corresponding to the QCD-based Hagedorn function, frequently used to fit the transverse momentum spectrum. The identified string tension fluctuations are heavy tailed, behaving similarly to the $q$-Gaussian distribution. 
After the convolution with the Schwinger mechanism, both approaches correctly describe the entire pT spectrum.
This approach is the onset for the nonthermal description of the particle production in ultrarelativistic pp collisions, exhibiting temperature fluctuations on small regions of the medium where the particles are created.
By analyzing the data of pp collisions at $\sqrt{s} =13$ TeV, we found that the average temperature associated with the Higgs boson production is around 85 times greater than the estimated value for the pT spectum of charged particles.
Our results show that the Higgs boson production exhibits the largest deviation from the thermal description.</abstract>
