SMEFT is an efficient tool to parametrize the effect of BSM physics in a model-independent way. We study di-Higgs and tri-Higgs productions at the muon collider which is parametrized by the dimension 6 mass operator. We also study di-boson and tri-boson processes which also include the production of Goldstone bosons. We discuss possible model dependence of multi-boson processes resulting from...
Motivated by new physics models which lead to final states containing a high multiplicity of bottom and top quarks; we developed a tagging strategy to suppress reducible and non-reducible multi-jet backgrounds. The idea takes advantage of the properties of light parton showers and of the gluon fragmentation into heavy quarks to reject jets that do not originate from a bottom quark. Preliminary...
Hadronization, a crucial component of event generation, is traditionally simulated using finely-tuned empirical models. While current phenomenological models have achieved significant success in simulating this process, there remain areas where they fall short in accurately describing the underlying physics. In this talk, I will introduce MLHAD, an alternative approach that supplants the...
