《量子場理論:解釋世界的神秘背景(英文)》是一部引進版權(quán)的英文科普著作,書名可譯為《量子場理論:解釋世界的神秘背景》。 量子場論(簡稱QFT)可以追溯到20世紀30年代,但是在那個時代,只有量子電動力學是確定存在的,還有其他關(guān)于QFT的理論研究,但作為解釋世界基本定律的理論,它得到全面認可是在20世紀60年代末到70年代初的那幾年,這些發(fā)展產(chǎn)生的結(jié)果構(gòu)成了所謂的粒子物理學標準模型,這個模型已經(jīng)被許多實驗觀察徹底地檢驗和證實了。它描繪了一幅可以被看作是概括量子電動力學的圖畫:物質(zhì)根據(jù)它的各種電荷與各種輻射相互作用。
羅伯特·勒戈(Roberto lengo),意大利國際高等研究院(SISSA)的教授,理論粒子物理小組的成員,曾擔任意大利國際高等研究院人文科學跨學科實驗室主任.他在量子場論和弦論等方面撰寫了許多專著,并且多年來一直為博士生教授量子場論的課程,
