abstract

The vector and axial-vector two-point functions are calculated to next-to-next-to-leading order in Chiral Perturbation Theory for three light flavours. We also obtain expressions at the same order for the masses, $m_\pi^2$, $m_K^2$ and $m_\eta^2$, and the decay constants, $F_\pi$, $F_K$ and $F_\eta$. We present some numerical results after a simple resonance estimate of some of the new ${\cal O}(p^6)$ constants.

  1. NLO observables for QCD-like theories and application to pion dark matter

    hep-ph 2025-09 conditional novelty 6.0 of 10

    NLO chiral perturbation theory for non-degenerate two-flavor real and pseudoreal gauge theories is derived, fitted to Sp(4) lattice data, and applied to pion dark matter self-interactions.

  2. Calculation of the axial-vector coupling constant $g_A$ to two loops in covariant chiral perturbation theory

    hep-ph 2025-05 conditional novelty 6.0 of 10

    The complete order-M^4 two-loop corrections to g_A are derived in EOMS and infrared covariant baryon chiral perturbation theory and evaluated with scattering-derived low-energy constants.

  3. Machine learning unveils the quark mass dependence of the pseudoscalar meson decay constants in three-flavour N$^2$LO ChPT

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    LASSO regression on LQCD data determines quark-mass dependence of f_π, f_K, f_η in N²LO three-flavor ChPT and supplies LECs for SU(3)-limit baryon mass predictions.

  4. Performance of Low Mode Averaging on Twisted-Mass Fermion Ensembles at the physical pion mass point

    hep-lat 2026-06 unverdicted novelty 4.0 of 10

    Numerical tests show low-mode averaging reduces noise in light meson and baryon observables on physical-pion twisted-mass ensembles, yielding renormalized chiral condensate 269.5(4.5) MeV.
