Summary
Five-dimensional quantum field theory is formulated by employing the invariant times as a useful parameter for quantizing field operators. It is shown that the quantization in terms of the invariant time is equivalent to the conventional quantization in terms of the ordinary time. The relation between five-dimensional quantum field theory and conventional quantum electrodynamics is also elucidated by taking discrete mass states for field operators.
Riassunto
Si formula la teoria dei campi quantistica a cinque dimensioni impiegando il tempo invariantes come parametro utile per quantizzare gli operatori di campo. Si mostra che la quantizzazione in termini del tempo invariante è equivalente alla quantizzazione convenzionale in termini del tempo ordinario. La relazione tra la teoria dei campi quantistica a cinque dimensioni e l'elettrodinamica quantistica convenzionale è chiarita prendendo stati di massa discreti per operatori di campo.
Резюме
Формируется пятимерная квантовая теория поля, используя инвариантное времяs, как параметр для квантования полевых опетаторов. Показывается, что квантование в терминах инвариантного времени эквивалентно обычному квантованию в терминах обычного времени. Обсуждается связь между пятимерной квантовой теорией поля и общепринятой квантовой электродинамикой, используя дискретные массовые состояния для полевых операторов.
