Description

We present results on 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. We extended our previous simulations with pion mass $m_\pi=$220 MeV [1] to physical pion mass $m_\pi=140$ MeV. Simulations are performed on $32^3\times8$ lattices using the highly improved staggered fermions with different values of lattice spacing corresponding to temperatures ranging from $144$ MeV to $166$ MeV. The magnetic field strength $eB$ is simulated with 9 different values up to $\sim$40$m_\pi^2$ at each temperature. We discuss the temperature and $eB$ dependences of the second-order fluctuations of and correlations among net baryon number, electric charge, and strangeness. We find that these fluctuations and correlations are substantially affected by the magnetic field at $eB~\sim$15$m_\pi^2$, which is around the strength produced in the initial stage of non-central heavy-ion collisions at the LHC energy. We propose that these fluctuations and correlations could be useful for probing the existence of a magnetic field in heavy-ion collision experiments.
