Axion is believed to be generated in the early universe, and it is<br \/>\nknown to be one of the candidates of cosmic dark matter. Many search experiments<br \/>\nwere performed, but the existence of axion has not been established yet.<br \/>\nFrom the recent observation on the cosmic microwave and the theoretical calculation,<br \/>\nit is suggested that the axion has a mass of O(100) eV. We are aiming to search for<br \/>\naxion in this mass region (New-CARRACK project).<br \/>\nIn the New-CARRACK project, we are planning to search for axion by using a single<br \/>\nphoton detection method. Single photon detection is free from the standard quantum<br \/>\nlimit and allows us to search for axion with a wide range of mass without degrading<br \/>\nits detection sensitivity. Besides, we proposed a new innovative method to search for<br \/>\naxion in a wide mass range by using photo-ionization processes.<br \/>\nIn this colloquium, the physics motivation to search for axion will be introduced, and<br \/>\nthe current status of the experimental search results will be reviewed. Then the<br \/>\noverview of New-CARRACK project and the preparation status will be shown.<\/p>\n","protected":false},"featured_media":0,"template":"","tags":[],"seminar_category":[55],"acf":{"s_now_accepting":true,"s_date_order":"2019-05-15 00:00:00","s_date_end":null,"s_date_text":"2019-05-15 00:00:00","s_text":"Atsushi Tokiyasu","s_place":"KMI Science Symposia (ES635)","s_place_other":"","s_categoryother":"","s_poster":"<p><a href=\"https:\/\/www.kmi.nagoya-u.ac.jp\/eng\/wp-content\/uploads\/sites\/2\/2019\/04\/KMI-Colloquim_Tokiyasu_20190515_poster.pdf\">KMI-Colloquim_Tokiyasu_20190515_poster<\/a><\/p>","s_poster2":"<p><a href=\"https:\/\/www.kmi.nagoya-u.ac.jp\/eng\/wp-content\/uploads\/sites\/2\/2019\/04\/KMI-Colloquim_Tokiyasu_20190515_poster-1.pdf\">KMI-Colloquim_Tokiyasu_20190515_poster<\/a><\/p>","s_slide":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.5 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Axion Seach Experiment, Past and Future - 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\/1334\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Axion Seach Experiment, Past and Future - KMI - Nagoya University\" \/>\n<meta property=\"og:description\" content=\"Axion is a hypothetical particle, originally proposed to solve the Strong CP problemin the QCD theory.
