These colliders oppositely accelerate electrons and positrons to collide at a certain point (so-called interaction point) where dedicated detectors are deployed. Such well-prepared collisions allow us to study unknown particles or phenomena that would unveil new physics. Among several electron positron colliders, our group has been involved in (1) Belle (II) experiment, whose accelerator ((Super)KEKB) has the world&#8217;s highest beam luminosity with a 3-kilometer rings located at KEK in Tsukuba, and (2) ILC project, whose linear accelerator is 20-kilometer-long aiming for world&#8217;s highest collision energies as a lepton collider.\n\n\n\n<p>Our research extends from the development of vertex detector, to the physics analysis using big data and machine learning techniques. Our students will have an opportunity to learn and deepen their understanding of their field while deciding on their research topic.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-2702\" src=\"https:\/\/epx.phys.tohoku.ac.jp\/wordpress\/wp-content\/uploads\/2025\/04\/DSCF1159-1-300x225.jpg\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/epx.phys.tohoku.ac.jp\/wordpress\/wp-content\/uploads\/2025\/04\/DSCF1159-1-300x225.jpg 300w, https:\/\/epx.phys.tohoku.ac.jp\/wordpress\/wp-content\/uploads\/2025\/04\/DSCF1159-1-1024x768.jpg 1024w, https:\/\/epx.phys.tohoku.ac.jp\/wordpress\/wp-content\/uploads\/2025\/04\/DSCF1159-1-768x576.jpg 768w, https:\/\/epx.phys.tohoku.ac.jp\/wordpress\/wp-content\/uploads\/2025\/04\/DSCF1159-1-1536x1152.jpg 1536w, https:\/\/epx.phys.tohoku.ac.jp\/wordpress\/wp-content\/uploads\/2025\/04\/DSCF1159-1-2048x1536.jpg 2048w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n\n\n\n<h2 class=\"toppage\">&nbsp; Research Descriptions<\/h2>\n\n\n\n<p>Our research descriptions can be found in the link below.<\/p>\n\n\n\n<p>In the &#8220;Research Description&#8221;, we introduce the physics motivation for high energy physics experiments and accelerators.
