At the end of the year MEG II collaboration: statistics increaseAt the Paul Scherrer Institute (PSI, Switzerland), the next six-month session of experimental data accumulation in the MEG II experiment to search for the decay µ+→e+γ has ended.A group of employees from the Department of Multiple Hadronic Processes (DMHP DLNP), that have been extensively participating in the MEG/MEG II collaboration for many years, successfully worked 137 eight-hour shifts during a session in remote access mode. The MEG II experiment is the second phase of the MEG experiment that was carried out at PSI from 2008 to 2013, in which a record limit on the upper limit of the relative decay probability B(µ+→e+γ)<4,2x10-13 (90% C.L.) was gained. The MEG II collaboration has continued to collect data throughout 2022 and 2023, with statistics expected to be ten times higher than in 2021 and a twentyfold increase in statistics projected by 2026, with the goal of achieving decay sensitivity µ+→e+γ before ~6,0x10-14.
