11. Multi Higgs Boson Signals of a Modified Muon Yukawa Coupling at a Muon Collider

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...

10. 2b or not 2b

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...

16. A Machine Learning Perspective on Hadronization Modeling with MLHAD

Ahmed Youssef (University of Cincinnati)

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...

6. Invariant amplitudes, unpolarized cross sections, and polarization observables in charged-current elastic neutrino-nucleon scattering

The (anti)neutrino-nucleon charged-current elastic scattering cross sections are parametrized by vector and axial form factors at leading order in weak and electromagnetic couplings. On the other hand, radiative corrections in the Standard Model, and potential new physics contributions beyond the Standard Model, can generate additional operators with corresponding invariant amplitudes. We...
