Branching fraction matrix of pair decays

Matrix of the different types of decays of a pair of Standard Model particles like the tau lepton, W boson, top, Higgs, …

Decay modes of two tau leptons (where τh stands for hadronic decay):SM_decay_matrix-001.pngBranching fractions of ditau decay:SM_decay_matrix-002.pngBranching fractions of ditau decay without charge sign, and the area proportional to the branching fraction:SM_decay_matrix-003.pngAlternative version:SM_decay_matrix-004.pngBranching fraction of a pair of top quarks (ttbar):SM_decay_matrix-005.pngAlternative version without charge signs:SM_decay_matrix-006.pngBranching fractions of a pair of Higgs bosons (areas are again proportional to the branching fraction):SM_decay_matrix-007.pngSM_decay_matrix-008.pngSM_decay_matrix-009.png
