摘要:

本文首次用手征改进(CI)费米子动力学方法模拟了各种强子的轴向电荷$G_A$。我们的工作与16^3 × 32晶格的空间范围2.4 fm,并使用变分方法与适当的基础雅可比涂抹插值抑制污染的激发态。

英文摘要:

We present first results from dynamical Chirally Improved (CI) fermion simulations for the axial charge $G_A$ of various hadrons. We work with 16^3x32 lattices of spatial extent 2.4 fm and use the variational method with a suitable basis of Jacobi-smeared interpolators to suppress contaminations from excited states.
