The production of a single top quark t in association with a W and a Z boson in proton-proton collisions has not been observed so far. Its small predicted cross section of 115 fb−1 at √s = 13 TeV and a large background from ttZ production make this process very challenging to study. However, tWZ production receives large contributions from beyond-the-standard-model (BSM) theories through the electroweak interaction of the top quark, making this process an important probe of BSM physics. In the context of the Standard Model Effective Field Theory (SMEFT), tWZ is sensitive to unitarity violating effects, leading to an anomalous growth of the cross section as a function of the energy.A search using Run 2 and 3 data collected by the CMS experiment at √s = 13 and 13.6 TeV offers the possibility to study tWZ with high significance. A status of the ongoing efforts is presented, including studies of the discriminating power of selected variables between tWZ and ttZ. Additionally, the sensitivity to different SMEFT dimension-6 operators is shown.
