...They were able to avoid the difficulties of divergence by using renormalization theory and obtain a finite answer. Around the same time, American Julian Seymour Schwinger (1918-94) constructed a similar theory, and American Richard Phillips Feynman (1918-88) invented a graph-based calculation method that made it possible to calculate electromagnetic phenomena with great precision. There was no effective calculation method for mesons, but in 1955 American Marvin Leonard Goldberger (1922- ) and others showed that a dispersion formula derived from the causal law that interactions occur locally agreed well with experiments, confirming the correctness of describing mesons in terms of local fields. ... *Some of the terminology that mentions "Schwinger, JS" is listed below.

…彼らはくりこみ理論により発散の困難を避け,有限の答えを得ることができた。同じころアメリカのシュウィンガーJulian Seymour Schwinger(1918‐94)も同様な理論を建設し,またアメリカのファインマンRichard Phillips Feynman(1918‐88)はグラフによる計算方法を発明し,これにより電磁現象をきわめて精確に計算できるようになった。 中間子に対しては有効な計算法がなかったが,55年アメリカのゴールドバーガーMarvin Leonard Goldberger(1922‐ )らは,相互作用が局所的に起こるという因果律から導かれる分散公式が実験とよく合うことを示し,中間子を局所的な場で記述することの正しさを確かめた。… ※「Schwinger,J.S.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
