- The pair-rate curve reaches its minimum near κλ ≈ 2.3 because the triangle and box contributions interfere destructively.
Field notes
The interface links a κλ slider to a collision-rate model, then lets readers compare two-photon and four-lepton evidence and switch to a CMS view. It gives the pair-production estimate as about one event per 2.5 trillion collisions and notes that ATLAS+CMS still allow κλ from −0.71 to 6.1 at 95% confidence. The author explicitly flags the 5.7σ figure as statistics-only.
