NSU Physics Department second-year undergraduate student Yevgeny Kovalenko and first-year graduate student Alexander Semenov received invitations to the SOKENDAI (Graduate University of Advanced Studies) summer school in Tskuba, Japan. The school is hosted by Japan鈥檚 largest national center for high energy physics, High Energy Accelerator Research Organization (KEK).
Semenov talked about the research that lead to his invitation,
Last year I worked on restoring tracks in an experiment measuring the anomalous magnetic moment of a muon. The primary problem is that a large number of particles fly through the detector in a short period of time (up to 30 particles in 5 nanoseconds). As a result, there are a large number of mixed traces of particle interaction with the detector. The application of classical methods to separate tracks reduces the problem to a huge amount of computation. To optimally solve the problem, it was suggested we use machine learning. The program managed to repeat the quality of the separation of tracks and speed up the calculation process several times. It was an extremely rewarding experience for me. The experiment is in the final stages of preparation. I was especially pleased this year when my application was approved again by the School selection committee.
The summer school students have a unique opportunity to participate in experiments in nuclear physics, elementary particle physics, and accelerator physics that are currently being conducted in the laboratories of KEK and the J-PARC proton accelerator center. Leading KEK and J-PARC scientists working on Belle II experiments head this research. Summer school last for two months which allows students to not only to get acquainted with the subject, but also to make a real contribution to the research.
Kovalenko and Semenov also work at the joint laboratory for studying the properties of b- and c-quarks in e + e-annihilation at the NSU Interdisciplinary Center for Elementary Particle Physics and Astrophysics and are actively involved in experiments conducted at the Institute of Nuclear Physics SB RAS.
