<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>The $Z_3$ symmetry imposes specific structures on the mass matrices of the Two Higgs Doublet Model (2HDM). These structures are parametrized by complex coefficients that must reproduce the observed quark masses and the CKM mixing matrix. We employ a Particle Swarm Optimization (PSO) algorithm to search for parameter values that satisfy these phenomenological constraints across different values of $\tan\beta$. We present a quantitative analysis of the elements of the mass matrices.</abstract>
