The mass differences between the excited mesons and their corresponding ground states are measured to be m(B*(+)) - m(B+) 45.277 +/- 0.039 +/- 0.027 MeV, m(B*(0))- m(B-0) = 45.471 +/- 0.056 +/- 0.028 MeV, and m(B-s(0)) - m(B-s(0)) = 49.407 +/- 0.132 +/- 0.041 MeV, where the first uncertainties are statistical and the second are systematic. These results improve on the precision of previous measurements by an order of magnitude.eninfo:eu-repo/semantics/openAccess#BAŞV!Article136310.1103/njf9-4zfv416514752-s2.0-105028620296Q1WOS:001691082300001Q10009-0003-0170-62080000-0003-3548-02620000-0003-2831-69820000-0002-7205-20400000-0003-2831-69820000-0002-3931-08450000-0003-0510-3810
