Description

We present the first lattice QCD results of the second order fluctuations of and correlations among net baryon number, electric charge and strangeness in (2+1)-flavor lattice QCD in the presence of a background magnetic field with physical pion mass $m_\pi$ = 135 MeV. To mimic the magnetic field strength produced in the early stage of heavy-ion collision experiments we use 6 different values of the magnetic field strength up to ∼10 $m_{\pi}^2$. The simulations were performed using the Highly Improved Staggered Quarks with physical pion mass on $N_\tau=8$ and 12 lattices. By comparing lattice QCD results to results from the hadron resonance gas model, possible proxies are proposed to study the imprints of magnetic fields in high-energy heavy ion collision experiments.
