SU(无穷大)主手征模型的关联函数

Correlation Functions of the SU(infinity) Principal Chiral Model

Axel Cortes Cubero, Peter Orland

摘要:

我们得到了SU(N)值裸场的(1+1)维非线性西格玛模型的物理算符的精确矩阵元,在t Hooft极限N趋于无穷大.具体地说,所有的形状因子的Noether电流和应力-能量-动量张量被发现与可积自助方法。这些形状因子用于找到这些算子的乘积的真空期望值。

英文摘要:

We obtain exact matrix elements of physical operators of the (1+1)-dimensional nonlinear sigma model of an SU(N)-valued bare field, in the 't Hooft limit N goes to infinity. Specifically, all the form factors of the Noether current and the stress-energy-momentum tensor are found with an integrable bootstrap method. These form factors are used to find vacuum expectation values of products of these operators.
