The 40th Belle II Japan Student Workshop took place at the High Energy Accelerator Research Organization (KEK) on March 13th, 2024. A total of 21 students participated from the fourth-year undergraduate, master, and doctoral courses of universities involved in the Belle II experiment. In this workshop, seven students, including three undergraduates and one doctoral student from our laboratory, gave presentations on their dissertation research. The workshop had lively discussions among the attendees and promoted their understanding of each other's research. The titles of the presentations by students from our laboratory are listed below.

〈 Graduation thesis presentations 〉
Shota Koji, "Test of MCP-PMTs with Cherenkov radiator for a muon beam monitor using electron beams."
Ayaka Kondo, "Evaluation of the bunch width monitor for the J-PARC muon g-2/EDM experiment and study on properties of the DRS4-based waveform digitizer."
Koichi Ueda, "Performance evaluation of gaseous photomultipliers with high time resolution using a photocathode with high quantum efficiency."

〈 Doctoral thesis presentation 〉
Kazuki Kojima, "Search for lepton flavor universality violation in \(\overline{B}\rightarrow D^{*}\tau^{-}\overline{\nu}_{\tau}\) decays using hadronic \(B\) tagging at the Belle II experiment."
