The Beijing Spectrometer III (BESIII) collaboration, a large team of researchers from universities worldwide conducting particle physics studies has recently reported the first observation of the leptonic decay D+→τ+ντ. This observation, presented in a paper published in Physical Review Letters, opens up the possibility of additional tests of mu/tau universality in D decays.
