Abstract

We have measured the vector-pseudoscalar mass splitting M(Ds*+)-M(Ds+)=144.22±0.47±0.37 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*0→D0γ, obtaining [M(Ds*+)-M(Ds+)]-[M(D*0)-M(D0)] =2.09±0.47±0.37 MeV. This is then combined with our previous high-precision measurement of M(D*0)-M(D0), which used the decay D*0→D0π0. We also measure the mass difference M(Ds+)-M(D+)=99.5±0.6±0.3 MeV, using the φπ+ decay modes of the Ds+ and D+ mesons.
