GPT-5.2 Derives New Result in Theoretical Physics

GPT-5.2 has produced a new result related to scattering amplitude, a core concept in theoretical physics. This research focuses on the interactions of gluons, the particles that mediate the strong nuclear force.

Under certain conditions (where one gluon has negative helicity and the rest have positive helicity), the existing physics community had assumed the amplitude to be zero. However, the researchers discovered that in a special region of momentum space called the half-collinear regime, this amplitude is not zero.

AI's role was decisive. GPT-5.2 Pro dramatically reduced the complexity of the expression obtained by human researchers through a complex Feynman diagram expansion, found a pattern applicable to all $n$, and conjectured the final formula.

Afterward, an internally scaffolded version of GPT-5.2 reasoned for about 12 hours to produce a formal proof establishing the validity of the formula. This result was analytically verified through Berends-Giele recursion and the soft theorem.
