Description
Heavy spin-one particles are well motivated new physics candidates that can have their origin in weakly coupled extensions of the Standard Model gauge group or in strongly coupled Composite Higgs models. Due to the variety of production and decay modes, Heavy Vector Triplets (HVT) are a useful benchmark for the study and comparison of future colliders. The Muon Collider is particularly suited for this search: I will present its potential of discovery in resonant and associated production, with leptonic or bosonic final states. Depending on coupling and channel, our differential likelihood analysis proves sensitive up to 5 times the centre of mass energy. We quantify the impact of the often neglected signal-background interference: HVT can have large decay width, making traditional analyses based on Narrow Width Approximation unviable. I will present simulation and analysis strategies applicable to all models featuring large widths.
