Measurement of the mass difference m(B(0))-m(B(+))
Using 230×106 BB̄ events recorded with the BABAR detector at the e+e- storage rings PEP-II, we reconstruct approximately 4100 B0→J/ψK+π- and 9930 B+→J/ψK+ decays with J/ψ→μ+μ- and e+e-. From the measured B-momentum distributions in the e+e- rest frame, we determine the mass difference m(B0)-m(B+)=(+...
