DESCRIPTION:Speakers: RODRÍGUEZ MELÉNDEZ\, Luz Silvana (Universidad Naci
 onal Autónoma de México)\nThe study of four-top-quark production\, $t\\b
 ar{t}t\\bar{t}$\, constitutes an important tool in the search for signals 
 of new physics\, due to its sensitivity to possible deviations from the pr
 edictions made within the Standard Model\, particularly in the heavy-parti
 cle and Higgs sectors. To exploit this sensitivity\, a precise description
  of the Standard Model processes that can imitate (background) this signal
  is required. Among these\, there are the $t\\bar{t}VV$ processes\, with $
 V=Z\,W$.\nIn this work\, we study top-quark pair production in association
  with two gauge bosons\, $t\\bar{t}VV$\, at next-to-leading-order (NLO) QC
 D corrections and their matching to parton showers\, which is is essential
  for an accurate description of the events that can be observed experiment
 ally\, matching that has been made within the POWHEG framework. The goal h
 as been to develop a Monte Carlo generator that provides a precise descrip
 tion of these processes. The resulting generator represents a tool for stu
 dying the properties of these background processes and for their incorpora
 tion into future phenomenological studies of four-top-quark production\, c
 ontributing to a more precise study of the most important backgrounds in s
 earches for new physics.\nThe dissemination of this type of work in precis
 ion collider physics can contribute to strengthening the field in Latin Am
 erica and fostering its development within the broader LHC community.\n\nh
