2+1维Yang-Mills理论:物质场耦合与弦断裂效应

Yang-Mills Theory in 2+1 Dimensions: Coupling of Matter Fields and String-breaking Effects

Abhishek Agarwal, Dimitra Karabali, V. P. Nair

摘要:

我们进一步探讨了规范不变矩阵变量下2+1维Yang-Mills理论的哈密顿形式。耦合到标量物质场的规范不变的领域进行了讨论。我们分析如何筛选伴随(和其他screenable)表示可以出现在这种形式主义。一个薛定谔方程,然后推导出的胶子态,这是一个伴随弦断裂时的子态。这个薛定谔方程的变分解导致弦断裂能量的分析估计是在最新的晶格估计的8.8%。

英文摘要:

We explore further the Hamiltonian formulation of Yang-Mills theory in 2+1 dimensions in terms of gauge-invariant matrix variables. Coupling to scalar matter fields is discussed in terms of gauge-invariant fields. We analyze how the screening of adjoint (and other screenable) representations can arise in this formalism. A Schrodinger equation is then derived for the gluelump states which are the daughter states when an adjoint string breaks. A variational solution of this Schrodinger equation leads to an analytic estimate of the string-breaking energy which is within 8.8% of the latest lattice estimates.
