ε区部分猝灭手征微扰理论

Partially quenched chiral perturbation theory in the epsilon-regime

Poul H. Damgaard, Hidenori Fukaya

摘要:

我们在部分猝灭的手征微扰理论中计算了ε区的介子介导子。价夸克质量和海夸克质量可以任意选择,并且都是非简并的。把一些海夸克的质量取到无穷大,我们就可以得到不同味数的理论之间的光滑联系,包括猝灭理论。这些结果可以直接与格点量子色动力学的模拟结果进行比较。

英文摘要:

We calculate meson correlators in the epsilon-regime within partially quenched chiral perturbation theory. The valence quark masses and sea quark masses can be chosen arbitrary and all non-degenerate. Taking some of the sea quark masses to infinity, one obtains a smooth connection among the theories with different number of flavors, as well as the quenched theory. These results can be directly compared with lattice QCD simulations.
