An S-matrix is the fundamental quantity in scattering theory. However, if a theory involves massless particles, such as QED and gravity, the conventional S-matrix has not been well defined due to the infrared divergence, and infrared dynamics thus needs to be understood in-depth to figure out the S-matrix...The book begins with introducing fundamental nature of the charge conservation law associated with asymptotic symmetry, and explaining its relations to soft theorems and memory effect. Subsequently it looks into an appropriate asymptotic state of the S-matrix without infrared divergences. The Faddeev-Kulish dressed state is known as a candidate of such a state, and its gauge invariant condition and its relation to the asymptotic symmetry are discussed. It offers an important building blocks for constructing the S-matrix without infrared divergences.. | | 出版日期 | Book 2021 | | 關(guān)鍵詞 | Infrared Divergence in S-matrix; Infrared Finite S-Matrix; Infrared Triangle; Faddeev-Kulish Dressed St | | 版次 | 1 | | doi | https://doi.org/10.1007/978-981-16-3045-3 | | isbn_softcover | 978-981-16-3047-7 | | isbn_ebook | 978-981-16-3045-3Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapor |
