Published a new paper with FSU theory colleagues: Prof. Takemichi Okui, Mitrajyoti Ghosh (postdoc), and Kevin Ligouri (Okui’s student).
[arXiv:2504.05378] JHEP 09 (2025) 144 Neutrino properties from muonium-antimuonium mixing M. Ghosh, K. Liguori, T. Okui, K. Tobioka

In this paper, we calculate the neutrino mass effect to muonium-antimuonium conversion process to address one of the central open questions in particle physics: are neutrinos are Majorana or Dirac fermions?
