DESCRIPTION:Speakers: Dr. PAREDES CRUZ\, Edier (Instituto de Física\, UNA
 M)\nWe present an ongoing study of $t\\bar{t}W^\\pm Z$ production aimed at
  improving the accuracy and reliability of theoretical predictions by comb
 ining fixed-order QCD calculations with parton-shower simulations. We cons
 ider next-to-leading order (NLO) QCD predictions matched to a Pythia parto
 n shower\, using the POWHEG framework as the primary matching approach and
  MadGraph-based calculations for cross-validation. The study will investig
 ate the impact of matching and parton-shower effects on inclusive rates an
 d kinematic distributions\, as\nwell as their associated theoretical uncer
 tainties. Particular attention will be given to the treatment of top-quark
  and electroweak-boson decays and\, where possible\, the preservation of s
 pin correlations. By comparing different implementations and simulation ap
 proaches\, we aim to establish a reliable description of $t\\bar{t}W^\\pm 
 Z$ production. This is especially relevant for studies of rare processes s
 uch as three- and four-top-quark production\, for which $t\\bar{t}W^\\pm Z
 $ is an important background.\n\nhttps://indico.nucleares.unam.mx/event/26
