标量QCD中的关联函数和约束

Correlation Functions and Confinement in Scalar QCD

Tajdar Mufti, Axel Maas

摘要:

一个理论的完整知识被编码在它的关联函数中。因此,非微扰效应,如QCD中的禁闭,必然包含在这些关联函数中。因此,许多约束方案对这些关联函数的行为进行预测。非微扰方法,如晶格计算,允许计算的关联函数和测试这些预测。为了避免手征对称性破缺的纠缠和费米子模拟的代价,这里标量QCD将被用作角色模型,因为它预计禁闭以同样的方式工作。我们目前的两点函数和三点函数的两种颜色和两种口味的标量的情况下的结果,并比较它们的预测。

英文摘要:

The complete knowledge of a theory is encoded in its correlation functions. Thus non-perturbative effects, like confinement in QCD, is necessarily contained in these correlation functions. As a consequence, a number of confinement scenarios make predictions for the behavior of these correlation functions. Non-perturbative methods, like lattice calculations, permit to calculate the correlation functions and test these predictions. To avoid the entanglement with chiral symmetry breaking and the costs of full fermion simulations, here scalar QCD will be used as a role model, as it is expected that confinement operates in the same way. We present results on both two-point functions and three-point functions for the case of two colors and two flavors of scalars, and compare them to the predictions.
