论文摘要
我们讨论在存在强背景磁场的情况下QCD的相图，提供数值证据，基于QCD的晶格模拟，$ 2+1 $ $ $ 1 $的口味和物理夸克质量，QCD交叉变成了足够大的磁场的一阶相变，并在$ eb = 4 $ GE = 4 $ GO $^2 $^2 $^2 $^2 $^2 $^2 $^$^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^2 $^$^2 $ $ t_c =（98 \ pm3）$ meV）和$ eb = 9 $ gev $^2 $（其中测得的临界温度为$ t_c =（63 \ pm5）$ mev）。
We discuss the phase diagram of QCD in the presence of a strong background magnetic field, providing numerical evidence, based on lattice simulations of QCD with $2+1$ flavours and physical quark masses, that the QCD crossover turns into a first order phase transition for large enough magnetic field, with a critical endpoint located between $eB=4$ GeV$^2$ (where we found an analytic crossover at a pseudo-critical temperature $T_c=(98\pm3)$ MeV) and $eB=9$ GeV$^2$ (where the measured critical temperature is $T_c=(63\pm5)$ MeV).
