Dressed state formalisms are a strong candidate for constructing the S-matrix. In this talk, I will review the S-matrix and long-range interactions. Then I will propose a dressed state formalism. This formalism can construct a finite S-matrix, at least in quantum electromagnetism. It also encompasses asymptotic symmetry and memory effect, as expected from Strominger\u2019s infrared triangle relation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>5\/30(\u6728)\u306b\u7b2c12\u56deCHS\u7269\u7406\u5b66\u79d1\u7814\u7a76\u30bb\u30df\u30ca\u30fc\u304c\u958b\u50ac\u3055\u308c\u307e\u3059\u306e\u3067\u3001\u4e0b\u8a18\u5185\u5bb9\u306b\u3054\u8208\u5473\u3042\u308b\u65b9\u306f\u662f\u975e\u3054\u8074\u8b1b\u304f\u3060\u3055\u3044\u3002\u5b66\u5185\u306e\u65b9\u306f\u7533\u3057\u8fbc\u307f\u4e0d\u8981\u3067\u3059\u306e\u3067\u3001\u6642\u9593\u306b\u306a\u308a\u307e\u3057\u305f\u3089\u76f4\u63a5\u6307\u5b9a\u5834\u6240\u306b\u304a\u8d8a\u3057\u304f\u3060\u3055\u3044\u3002\u5b66\u5916\u304b\u3089\u3044\u3089\u3063\u3057\u3083\u308b\u65b9\u306f\u3001 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_coblocks_attr":"","_coblocks_dimensions":"","_coblocks_responsive_height":"","_coblocks_accordion_ie_support":"","footnotes":""},"categories":[5,3],"tags":[],"class_list":["post-1417","post","type-post","status-publish","format-standard","hentry","category-news","category-whats-new"],"_links":{"self":[{"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/posts\/1417","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/comments?post=1417"}],"version-history":[{"count":3,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/posts\/1417\/revisions"}],"predecessor-version":[{"id":1426,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/posts\/1417\/revisions\/1426"}],"wp:attachment":[{"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/media?parent=1417"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/categories?post=1417"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.phys.chs.nihon-u.ac.jp\/yamamoto\/wp-json\/wp\/v2\/tags?post=1417"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
