论文摘要
我们研究了晶格QCD结果对夸克动态质量对't Hooft scapendant stepend延长的nambu-Jona-lasinio模型在光和奇怪的夸克扇区（\ emph {up}，\ emph {down}和\ emph {sanky}）中的磁场依赖性的含义。参数空间在消失的磁场上，使用夸克动态质量和介子光谱受到约束，而在非呈磁场强度下，两个夸克风味的动力质量的依赖性用于符合磁场的依赖性，以依赖于模型耦合，两者均构成了四个feRmion nambu-jona-jona-jona-jona-inambu-jona-inambu-jona-lasinio互动和六个互动。我们发现，该过程再现了反磁性催化，标量耦合的强度与磁场降低，而六倍屈服的强度随着磁场而增加。
We study the implications of recent lattice QCD results for the magnetic field dependence of the quarks dynamical masses on the 't Hooft determinant extended Nambu--Jona-Lasinio Model in the light and strange quark sectors (\emph{up}, \emph{down} and \emph{strange}). The parameter space is constrained at vanishing magnetic field, using the quarks dynamical masses and the meson spectra, whereas at non-vanishing magnetic field strength the dependence of the dynamical masses of two of the quark flavors is used to fit a magnetic field dependence on the model couplings, both the four-fermion Nambu--Jona-Lasinio interaction and the six-fermion 't Hooft flavor determinant. We found that this procedure reproduces the inverse magnetic catalysis, and the strength of the scalar coupling decreases with the magnetic field, while the strength of the six-fermion 't Hooft flavor determinant increases with the magnetic field.
