Feeler stylus and dial gauge: Higgs decay signal strength modifier μ and Lilith-2 likelihood
Dual coupling goniometers: vector boson (CV) and fermion (CF) reduced coupling modifiers
An isometric physical explainer of consigcody94/pythia-mcp. The decay carriage steps six Higgs boson decay channels (diphoton, four-lepton, WW, bottom pair, tau pair, dimuon) beneath a quadrupole collision chamber and dual coupling goniometer station. The feeler stylus measures branching fraction step height while dual vernier dials register gauge boson (CV) and fermion (CF) reduced couplings, displaying signal strength modifiers calibrated against LHC Run 2 and Run 3 experimental datasets.
