SU($\infty$)主手征模型中的算符乘积

Operator Products in the SU($\infty$) Principal Chiral Model

Peter Orland

AI总结:

本文研究SU($\infty$)主手征模型的算符乘积,回顾局域算符形状因子与精确两点函数,并讨论非真空乘积,旨在从公理化形式体系重建拉格朗日场论。

摘要:

SU($N$)主手征模型在$1+1$维中具有渐近自由性和可积性。在大$N$极限下,虽然不存在散射,但关联函数并非自由场论的关联函数。我们简要回顾局域算符形状因子的推导。此类算符的两点函数已可精确求得。标度场算符的两点函数具有重整化群所预期的短距离行为。我们简要讨论非真空算符乘积。最终目标是从这种公理化量子场论形式体系导出拉格朗日场论。

英文摘要:

The SU($N$) principal chiral model is asymptotically free and integrable in $1+1$ dimensions. In the large-$N$ limit, there is no scattering, but correlation functions are {\em not} those of a free field theory. We briefly review the derivation of form factors for local operators. Two-point functions for such operators are known exactly. The two-point function of scaling-field operators has the short-distance behavior expected from the renormalization group. We briefly discuss non-vacuum operator products. The ultimate goal is to derive the Lagrangian field theory from this axiomatic quantum-field-theory formalism.
