Understanding the problem

Read the background

Standard vanishing arguments apply at generic kinematics. The authors first calculated low-multiplicity examples; the new formula extends the specified decay-region result to arbitrary multiplicity.

Why it matters

An analytical advance for a defined amplitude family, with a general-multiplicity formula. Its significance is restricted to the stated kinematics.

What counts as progress

A sourced analytical result, substantive numerical advance, or useful calculation method with its physical model, approximation, baseline, and AI contribution stated.

What to watch for

  • Compare the same physical model, kinematic region, and approximation.
  • This does not overturn vanishing at generic physical kinematics or demonstrate an observed particle decay. The paper reports author checks, not an independent audit. AIProofWatch has not checked the derivation or run a formal prover.
  • Track independent checks and subsequent corrections separately from importance.
