This contribution presents an investigation into the electroweak production of same-sign W boson pairs (ssWW) with a hadronically decaying tau lepton ($\tau_h$) in the final state. This study is based on proton-proton collisions at a center-of-mass energy of 13 TeV, as recorded by the CMS experiment at the CERN LHC, with an integrated luminosity of 138 fb$^{-1}$. This work delves deeper into the electroweak spontaneous symmetry breaking (EWSB) sector of the standard model (SM) of particle physics, focusing on Vector Boson Scattering (VBS) processes, which play a pivotal role in understanding the non-abelian structure of the SM. The article introduces a Machine Learning approach to enhance the identification of the final state in ssWW VBS processes. The results show an observed electroweak signal strength of $1.44_{−0.56}^{+0.63}$​, corresponding to a signal significance of 2.74 standard deviations. The study concludes with the intention to explore the sensitivity to indirect New Physics effects using the Standard Model Effective Field Theory (SMEFT) framework.
