abstract

  • We have measured the vector-pseudoscalar mass splitting M(Ds*+)-M(Ds+)=144.220.470.37 MeV significantly more precisely than the previous world average. We minimize the systematic errors by also measuring the vector-pseudoscalar mass difference M(D*0)-M(D0) using the radiative decay D*0D0, obtaining [M(Ds*+)-M(Ds+)]-[M(D*0)-M(D0)] =2.090.470.37 MeV. This is then combined with our previous high-precision measurement of M(D*0)-M(D0), which used the decay D*0D00. We also measure the mass difference M(Ds+)-M(D+)=99.50.60.3 MeV, using the + decay modes of the Ds+ and D+ mesons. © 1994 The American Physical Society.
