GAYANE GHEVONDYAN

Montebello

Summary

  • I accomplished my Ph.D. in Elementary Particle Physics in February 2025. Since 2021, I have been an active member of the Belle II experiment. During these years, I worked with the ARICH group, focusing on ARICH statistical checks. My Ph.D. thesis was dedicated to studying ARICH efficiency and misidentification (misID) in the Belle II experiment by reconstructing D decays. In the past year, I was involved in invisible particle studies with the Yerevan Belle II group. Earlier in my academic career, I participated in the DESY Summer School in 2019, where I worked with the Tau group for approximately two months on tau-related studies. In addition to my research activities, I have actively contributed to Belle II operations by participating in various shifts, including Software Quality, Data Production, CR Navigator, ARICH Remote, and ARICH Local shifts.
