CP-Odd Information Flow in H → ZZ* → 4ℓ: Imaginary Spin Correlations and Virtuality-Resolved Tomography

CP-Odd Information Flow in H → ZZ* → 4ℓ: Imaginary Spin Correlations and Virtuality-Resolved Tomography We quantify how much CP-odd Higgs information survives compression into spin-correlation moments in H → ZZ* → 4ℓ. In a specified leading-order model, a real ε = a3/a1 deformati...

Weight Concentration and Category Heterogeneity in Precision Higgs Combinations: A Robustness Bound from H → μ⁺μ⁻

Weight Concentration and Category Heterogeneity in Precision Higgs Combinations: A Robustness Bound from H → μ⁺μ⁻ Precision Higgs measurements combine production-sensitive categories under a common signal strength. This paper quantifies how residual category effects change the co...

Permutation Symmetry Selection Rules and Ultraviolet Transfer Suppression in Graph Laplacian Propagators

Permutation Symmetry Selection Rules and Ultraviolet Transfer Suppression in Graph Laplacian Propagators We study transfer between distinct sources in positive, second-order scalar theories whose mass mixing is a graph Laplacian. A ten-vertex shared-anchor graph carries an S₃ × S...

Information Flow in H → ZZ* → 4l: Spin-Qutrit Tomography of a Real CP-Even a2 Deformation

Quantum entanglement between massive Z bosons produced in Higgs-boson decays has recently become experimentally accessible at the Large Hadron Collider. In H → ZZ(*) → 4l, the two spin-1 Z bosons form an entangled spin-qutrit system whose polarization and spin-correlation structu...
