Description
We present a lattice QCD study of light pseudoscalar meson masses and decay constants in strong background magnetic fields, using three different lattice sizes. Our simulations employ (2+1)-flavor ensembles using the highly improved staggered quark (HISQ) action with physical quark masses and three values of the lattice spacing ($a \approx$ 0.067, 0.084, 0.112 fm) to enable a controlled continuum extrapolation. We utilized seven different values of the magnetic field strength, reaching up to $ \sim 1.22 \mathrm{GeV}^2 ( \sim 66 M_\pi^2$ ) in the vacuum. The meson masses and decay constants were extracted from the exponential decay and amplitudes of two-point correlation functions. Finally, we analyze how these quantities depend on the magnetic field, providing insight into mesonic behavior in strong magnetic backgrounds.
