| contents | The addition of a heavy charged vector gauge boson ${\mathbf{W}}^\prime$ to the Standard Model (SM) with negligible quark couplings ("quarkophobic") and triple gauge couplings can address issues with the SM, such as the B-meson anomalies and recent discrepancies in the W boson mass measurements. We present a phenomenology study probing ${\mathbf{W}}^\prime$ production through weak boson fusion in proton-proton collisions at the Large Hadron Collider. We operate under a simplified model with a large ${\mathbf{W}}^\prime$ decay width and consider final states with two jets, large missing transverse momentum, and one light lepton. Notably, we use point cloud learning for the first time in a BSM search$\unicode{x2014}$specifically, a novel Lorentz-Equivariant Geometric Algebra Transformer$\unicode{x2014}$providing significant improvement in signal sensitivity compared to traditional methods. |
