伪粒子方法中的伴随弦破缺

Adjoint string breaking in the pseudoparticle approach

Christian Szasz, Marc Wagner

摘要:

我们将赝粒子方法应用于SU(2)Yang-Mills理论,详细研究了各种表象下两个静电荷之间的势。而对于基本表象中的电荷,我们发现一个线性上升的限制势,我们清楚地观察到弦断裂,当考虑伴随表象中的电荷时。我们还演示了Casimir标度,并计算了不同自旋和宇称下的胶泵质量。数值结果与格点结果定性一致。

英文摘要:

We apply the pseudoparticle approach to SU(2) Yang-Mills theory and perform a detailed study of the potential between two static charges for various representations. Whereas for charges in the fundamental representation we find a linearly rising confining potential, we clearly observe string breaking, when considering charges in the adjoint representation. We also demonstrate Casimir scaling and compute gluelump masses for different spin and parity. Numerical results are in qualitative agreement with lattice results.
