Description
We studied the temporal correlation functions for mesons in different channels in (2+1)-flavor QCD in the presence of external magnetic fields at zero temperature. The simulations were performed on $32^3 \times 96$ lattices using the Highly Improved Staggered Quarks (HISQ) action with $m_{\pi}$ around 230 MeV. The strength of magnetic fields range in $ 0 < |eB| ≲ 3\ \text{GeV}^2$. We found that the effective mass of $\pi_0$ obtained from connected part of Green function decreases as the magnetic field grows. We also studied the meson mass in the vector channel and will discuss the possible relation with superconductivity under a strong external magnetic field.
