XXI Mexican School on Particles and Fields 2026
<p style="text-align:justify">The <strong>XXI Mexican School on Particles and Fields</strong> takes place from <strong>October 19th to 23rd, 2026</strong>, in the city of Puebla, Puebla, México. The format of the school is 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 México. </p>
<p style="text-align:justify">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. </p>

We present an ongoing study of $t\bar{t}W^\pm Z$ production aimed at improving the accuracy and reliability of theoretical predictions by combining fixed-order QCD calculations with parton-shower simulations. We consider next-to-leading order (NLO) QCD predictions matched to a Pythia parton shower, using the POWHEG framework as the primary matching approach and MadGraph-based calculations for cross-validation. The study will investigate the impact of matching and parton-shower effects on inclusive rates and kinematic distributions, as
well as their associated theoretical uncertainties. Particular attention will be given to the treatment of top-quark and electroweak-boson decays and, where possible, the preservation of spin correlations. By comparing different implementations and simulation approaches, we aim to establish a reliable description of $t\bar{t}W^\pm Z$ production. This is especially relevant for studies of rare processes such as three- and four-top-quark production, for which $t\bar{t}W^\pm Z$ is an important background.
