We introduce photons in Partially Quenched Chiral Perturbation Theory and calculate the resulting electromagnetic loop-corrections at NLO for the charged meson masses and decay constants. We also present a numerical analysis to indicate the size of the different corrections. We show that several phenomenologically relevant quantities can be calculated consistently with photons which couple only to the valence quarks, allowing the use of gluon configurations produced without dynamical photons.

Discussion (0). Continue with ORCID to comment.

  1. Checks on QED and strong-isospin breaking corrections to $a_{\mu}^{\mathrm{HVP}}$

    hep-lat 2025-02 conditional novelty 4.0 of 10

    New cross-checks using exact derivatives, low-mode averaging, and finer ensembles confirm the earlier BMW QED and strong-isospin breaking corrections to a_mu^HVP.

  2. Hybrid calculation of hadronic vacuum polarization in muon g-2 to 0.48\%

    hep-lat 2024-07 unverdicted novelty 4.0 of 10

    Lattice QCD on finer grids yields a_μ^LO-HVP = 715.1(3.4)×10^{-10}, producing a standard-model prediction for a_μ that differs from experiment by only 0.5 sigma.

    The FLAG 2024 review provides updated averages of lattice QCD determinations for quark masses, decay constants, form factors, mixing parameters, and nucleon matrix elements.
