Sum rules and covariance

Chiral Symmetry Currents and Current Algebras

Abstract

A representation of commutator matrix elements is derived in Lehmann-Symanzik-Zimmermann formalism and applied to current density algebra sum rules in an arbitrary frame of reference. The sum rules take a remarkably simple form if the current correlation functions obey multiple integral representations in the current masses. The reference frame dependence of the sum rules becomes explicit.

Правила сумм и ковариантность

Резуме

Представление коммутаторных матричных элементов производится от формализма Лемана-Симанцика-Циммермана и применяется к правилам сумм алгебры токов в любой системе отчета. Правила сумм принимают особенно простую форму в случае, если корреляционные функции тока подчиняются интегральным представлениям в массах токов. Зависимость правил сумм от системы отчета становится явной.
