用二味非局部NJL模型约束$U(1)_A$对称破缺的强度

Constraining the strength of $U(1)_A$ symmetry breaking using 2-flavour non-local NJL model

Mahammad Sabir Ali, Chowdhury Aminul Islam, Rishi Sharma

摘要:

在有磁场存在的情况下,我们利用LQCD数据对非定域的两味NJL模型中的t Hooft行列式项的强度进行了系统的分析。与轴对称性有关的拓扑磁化率也被计算,并与LQCD结果进行了比较,进一步验证了我们的计算。

英文摘要:

In presence of magnetic field we have done a systematic analysis to constrain the strength of 't Hooft determinant term using LQCD data within a non-local version of two flavour NJL model. Topological susceptibility, being related to the axial symmetry, have also been calculated and compared with LQCD results to further validate our calculation.
