abstract

An impact of nonperturbatively-treated soft gluon modes on the value of anomalous magnetic moment of muon $a_\mu$ is studied within the mean-field approach to QCD vacuum and hadronization. It is shown that radial excitations of vector mesons strongly enhance contribution of hadronic vacuum polarization to $a_\mu$, doubling the contribution of one intermediate meson processes compared to result for ground state mesons. The mean field also strongly influences the hadronic light-by-light scattering contribution due to the Wilson line in quark propagators.

  1. Gravitational form factors of pion in a nonlocal quark model

    hep-ph 2025-07 conditional novelty 6.0 of 10

    In a nonlocal quark model, the pion gravitational form factors are calculated, with bubble diagrams contributing about 8% of A(0) and 69% of D(0).

  2. The light-by-light contribution to the muon g-2 within the nonlocal chiral quark model with vector and axial-vector mesons

    hep-ph 2025-04 conditional novelty 5.0 of 10

    The nonlocal chiral quark model with vector and axial-vector mesons yields a hadronic light-by-light contribution to the muon g-2 of (157±10.6)x10^-11, with vector-meson photon dressing contributing only a few units.
