Chiral Anomaly in the *H&sup((')) *>*p*+*p*-*g and *h&sup((')) *>*p*+*p*-l*+l*- Decays / M.K.Volkov, A.A.Osipov, K.Nurlan, A.A.Pivovarov. – Text : electronic // Physical Review D. – 2026. – Vol. 114, No. 3. – P. 034044. – URL: https://doi.org/10.1103/fvck-n7xd. – Bibliogr.: 77.
We report the presence of a flavor-violating correction to the 𝑉𝐴𝐴𝐴-type anomaly, 𝛿(′), induced by the surface terms of the anomalous quark triangle diagram, previously found in the 𝜂,𝜂′ →𝜋+𝜋−𝛾 decay amplitudes, and investigate its impact on the corresponding semileptonic decay modes of 𝜂 and 𝜂′. The magnitude of 𝛿(′) can be set from the experimental data on the 𝜂(′) →𝜋+𝜋−𝛾 decay width. We then estimate another low-energy constant, the slope parameter 𝛼(′). The impact of different schemes for describing 𝜂 −𝜂′ mixing on the value of 𝛿(′) and 𝛼(′) is discussed. The predictions are shown to be in complete agreement with the available experimental data.
