Maurice Anderson, PhD student in our CRC, received the First Prize for Best Poster Presentation at the MESON 2026 Conference.
Maurice was recognized for his poster “Dark Photon Search at BESIII using Initial State Radiation.” The work presents a new search for the production and visible decay of a massive dark photon using BESIII data. The analysis exploits the newly acquired BESIII data taken at the Ψ(3770) resonance to search for a narrow dark photon resonance in the dilepton invariant mass spectrum.
The award recognizes the scientific quality of Maurice’s work and highlights the contributions of CRC 1660’s early-career researchers to the international particle physics community. Congratulations to Maurice on this well-deserved achievement!
