Complete Next-to-Next-to-Leading-Order QCD Correction to $J/\psi \to 3\gamma$ Decay

Bin Gong, Chao Zeng, Cong Li, Jian-Xiong Wang, Ruichang Niu, Xu-Dong Huang

Amplitude-level NRQCD factorization yields the first complete NNLO QCD correction to J/ψ → 3γ, producing a positive decay width of 0.96 eV that aligns with BESIII data.

Claims

C1strongest claim

We present the first complete next-to-next-to-leading-order (NNLO) QCD correction to the decay J/ψ → 3γ. The resulting partial width Γ(J/ψ → 3γ) = 0.96^{+4.32}_{-0.13} eV shows markedly improved agreement with the BESIII measurement.

C2weakest assumption

The assumption that amplitude-level NRQCD factorization provides a systematic prescription resolving negative rates, and that the perturbative series converges sufficiently at NNLO despite dominant renormalization scale variation.

C3one line summary

First complete NNLO QCD correction to J/ψ → 3γ gives partial width 0.96 eV that aligns better with BESIII measurement.
