General properties of interaction currents of higher spin fermions and their consequences for πN–scattering

General properties of interaction currents of higher spin fermions and their consequences for πN–scattering

The model for the currents of interactions of higher spin fermions with the 0- and 1/2-spin particles is proposed. These currents obey to the theorem on currents and fields as well as the theorems on current asymptotics. The comparison of the proposed model with partial wave analysis of the πN–scatt...

Предложена модель для токов взаимодействий высокоспиновых фермионов с частицами, обладающими спином 0 и 1/2. Эти токи удовлетворяют теореме о токах и полях и теореме об асимптотике токов. Сравнение предложенной модели с парциально волновыми анализами πN–рассеяния в области Δ(1232) показывает справедливость теоремы о токах и полях. Показано, что вследствие теоремы об асимптотике токов вклады высокоспиновых нуклонных резонансов в амплитуды πN–рассеяния должны убывать при высоких энергиях по крайней мере как s⁻⁶. Запропоновано модель для струмів взаємодій високоспінових ферміонів з частинками, які мають спін 0 та 1/2. Ці струми задовольняють теоремі про струми та поля та теоремі про асимптотику струмів. Порівняння запропонованої моделі з парціально хвильовими аналізами πN–розсіювання в області Δ(1232) показує справедливість теореми про струми і поля. Показано, що внаслідок теореми про асимптотику струмів внески високоспінових нуклонних резонансів в амплітуди πN–розсіювання повинні спадати при високих енергіях по меншій мірі як s⁻⁶. 2012 Article General properties of interaction currents of higher spin fermions and their consequences for πN–scattering / Yu.V.
