Experimentally, both can be probed through the production of Higgs boson pairs (HH), a rare process that is one of the milestones of Higgs physics at the LHC.<\/p>\n<p>In this seminar, the latest HH searches at the LHC are reported, with emphasis on the results obtained with the full LHC Run 2 at 13 TeV and Run 3 at 13.6 TeV datasets. Non-resonant HH search results are interpreted both in terms of sensitivity to the Standard Model and as limits on the Higgs boson self-coupling and the quartic VVHH coupling. Studies based on current analyses have been carried out to understand the expected precision of these measurements at the High Luminosity LHC (HL-LHC). Prospects for di-Higgs results assuming a dataset of 3 ab-1 at the HL-LHC will also be presented.<\/p>\n<hr>\n<p>\u6a19\u6e96\u6a21\u578b\u306f\u3001\u30d2\u30c3\u30b0\u30b9\u7c92\u5b50\u306e\u81ea\u5df1\u7d50\u5408\u304a\u3088\u3073\u30d2\u30c3\u30b0\u30b9\u30dd\u30c6\u30f3\u30b7\u30e3\u30eb\u306e\u5f62\u72b6\u306b\u3064\u3044\u3066\u660e\u78ba\u306b\u4e88\u6e2c\u3067\u304d\u307e\u3059\u3002\u3053\u308c\u3089\u306f\u30d2\u30c3\u30b0\u30b9\u7c92\u5b50\u5bfe\u751f\u6210\uff08HH\uff09\u3092\u901a\u3058\u3066\u5b9f\u9a13\u7684\u306b\u8abf\u3079\u308b\u3053\u3068\u304c\u3067\u304d\u307e\u3059\u3002\u3053\u306e\u904e\u7a0b\u306f\u975e\u5e38\u306b\u7a00\u3067\u3042\u308a\u3001LHC\u306b\u304a\u3051\u308b\u30d2\u30c3\u30b0\u30b9\u7269\u7406\u306e\u91cd\u8981\u306a\u30de\u30a4\u30eb\u30b9\u30c8\u30fc\u30f3\u306e\u4e00\u3064\u3067\u3059\u3002<\/p>\n<p>\u3053\u306e\u30bb\u30df\u30ca\u30fc\u3067\u306f\u3001LHC\u306b\u304a\u3051\u308b\u6700\u65b0\u306eHH\u63a2\u7d22\u306b\u3064\u3044\u3066\u5831\u544a\u3057\u307e\u3059\u3002\u3068\u304f\u306b\u300113 TeV\u3067\u306eLHC\u30e9\u30f32\u304a\u3088\u307313.6 TeV\u3067\u306e\u30e9\u30f33\u306e\u5168\u30c7\u30fc\u30bf\u30bb\u30c3\u30c8\u3092\u7528\u3044\u305f\u7d50\u679c\u306b\u7126\u70b9\u3092\u5f53\u3066\u307e\u3059\u3002\u975e\u5171\u9cf4HH\u63a2\u7d22\u306e\u7d50\u679c\u306f\u3001\u6a19\u6e96\u6a21\u578b\u306b\u5bfe\u3059\u308b\u611f\u5ea6\u3001\u304a\u3088\u3073\u30d2\u30c3\u30b0\u30b9\u7c92\u5b50\u306e\u81ea\u5df1\u7d50\u5408\u3084VVHH\u306e\u56db\u91cd\u7d50\u5408\u306b\u5bfe\u3059\u308b\u5236\u9650\u3068\u3057\u3066\u89e3\u91c8\u3067\u304d\u307e\u3059\u3002\u3055\u3089\u306b\u3001\u73fe\u5728\u306e\u89e3\u6790\u306b\u57fa\u3065\u304d\u3001\u5c06\u6765\u306e\u9ad8\u8f1d\u5ea6LHC\uff08HL-LHC\uff09\u306b\u304a\u3051\u308b\u6e2c\u5b9a\u7cbe\u5ea6\u306b\u3064\u3044\u3066\u3082\u691c\u8a0e\u3057\u307e\u3057\u305f\u3002HL-LHC\u3067\u306e3 ab<sup>-1<\/sup>\u306e\u30c7\u30fc\u30bf\u30bb\u30c3\u30c8\u3092\u4eee\u5b9a\u3057\u305f\u5834\u5408\u306edi-Higgs\u6e2c\u5b9a\u306e\u5c55\u671b\u306b\u3064\u3044\u3066\u3082\u7d39\u4ecb\u3057\u307e\u3059\u3002<\/p>\n","protected":false},"featured_media":0,"template":"","tags":[],"seminar_category":[154],"acf":{"s_now_accepting":true,"s_date_order":"2025-12-18 15:10:00","s_date_end":"2025-12-18 16:10:00","s_date_text":"15:10 - 16:10","s_text":"Arely Cortes Gonzalez (ATLAS Higgs Convener, ICEPP, Tokyo)","s_place":"ES635 + Zoom","s_place_other":"","s_categoryother":"","s_poster":"","s_poster2":"","s_slide":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.5 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>HH at LHC and beyond: Review of latest results and future prospects - KMI - Nagoya University<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.kmi.nagoya-u.ac.jp\/eng\/seminar\/3450\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"HH at LHC and beyond: Review of latest results and future prospects - KMI - Nagoya University\" \/>\n<meta property=\"og:description\" content=\"The Standard Model makes a definite prediction for the Higgs boson self-coupling and thereby the shape of the Higgs potential.
