At the LHC, NTGCs are searched for via the process pp → ZZ → 4l, where the two Z-bosons are on-shell. In this paper, we discuss how the same process can occur through tree-level diagrams just adding a vector-like quark (VLQ) to the standard model. Since NTGCs are generated in standard model effective theory (SMEFT) only at 1-loop order, vector like quarks could be an important alternative interpretation to, and background for, NTGC searches. Here, we construct a simple example model, discuss low-energy constraints and estimate current and future sensitivities on the model parameters from pp → ZZ → 4l searches.}, organization = {Grant CEX2023-001292- S from MCIU/AEI}, organization = {Generalitat Valenciana under the grants GRISOLIAP/2020/145 and PROMETEO/2021/083}, organization = {Grants PID2023-147306NB-I00 and CIPROM/2021/054 (Generalitat Valenciana)}, organization = {MCIN/AEI/10.13039/501100011033 and the European Union NextGenerationEU/PRTR under the grant JDC2022-048687-I and partially funded by Grant AST22_6.5 (Consejeria de Universidad, Investigacion e Innovacion and Gobierno de España and Union Europea NextGenerationEU)}, organization = {Generalitat Valenciana PROMETEO/2021/083, Proyecto Consolidacion CNS2022-135688, and the Ministerio de Ciencia e Innovacion PID2020 -113644GB-I00}, publisher = {Springer Nature}, keywords = {SMEFT}, keywords = {Specific BSM Phenomenology}, title = {Faking ZZZ vertices at the LHC}, doi = {10.1007/JHEP12(2024)098}, author = {Cepedello Pérez, Ricardo and Esser, Fabian and Hirsch, Martin and Sanz, Veronica}, }
