Analytical calculation of a fourth-order vacuum polarization coefficient

Аналитическое вычисление коэффициента ноляризации вакуума четвертого порядка

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

Using the result of Gorishny, Kataev and Larin for the fourth-order Gell-Mann-Low function, we have analytically extracted the coefficient of the single power of logarithm occurring in the fourth-order vacuum polarization in the asymptotic expansion of the renormalized photon propagator.

Riassunto

Usando il risultato di Gorishny, Kataev e Larin per la funzione di Gell-Mann-Low di quart'ordine, si è ricavato analiticamente il coefficiente della potenza singola del logaritmo presente nella polarizzazione del vuoto di quart'ordine nello sviluppo asintotico del propagatore di fotoni rinormalizzato.

Резюме

Используя результат Горичного, Катаева и Ларина для функции Гелл-Манна-Лоу четвертого порядка, мы аналитически извлекаем коэффициент первой степени логарифма, который появляется в поляризации вакуума четвертого порядка в асимптотическом разложении перенормированного фотонного пропагатора.
