The SMEFT contribution to the amplitude of the $2\\to3$ VBS processes, taking $W_L W_L\\rightarrow W_L W_L h$ and $W_L W_L\\rightarrow h h h$ as examples, exhibits enhancement with the energy $\\frac{\\mathcal{A}^{\\text{BSM}}}{\\mathcal{A}^{\\text{SM}}} \\sim \\frac{E^2}{\\Lambda^2}$, which indicates the sensitivity of these processes to the related dimension-six operators in SMEFT.
