We measure the masses of b hadrons in exclusively reconstructed final states containing a J/psi --> mu-mu+ decay using 220 pb(-1) of data collected by the CDF II experiment. We find: m(B+) = 5279.10 +/- 0.41(stat.) +/- 0.36(sys.) MeV/c2, m(B0) = 5279.63 +/- 0.53(stat.) +/- 0.33(sys.) MeV/c2, m(B(s)0) = 5366.01 +/- 0.73(stat.) +/- 0.33(sys.) MeV/c2, m(lambda(b)0) = 5619.7 +/- 1.2(stat.) +/- 1.2(sys.) MeV/c2. m(B+) - m(B0) = -0.53 +/- 0.67(stat.) +/- 0.14(sys.) MeV/c2, m(B(s)0) - m(B0) = 86.38 +/- 0.90(stat.) +/- 0.06(sys.) MeV/c2, m(lambda(b)0) - m(B0) = 339.2 +/- 1.4(stat.) +/- 0.1(sys.) MeV/c2. The measurements of the B(s)0, lambda(b)0 mass, m(B(s)0) - m(B0) and m(lambda(b)0) - m(B0) mass difference are of better precision than the current world averages.
我们使用CDF II实验收集的220皮靶⁻¹数据，在仅重建的包含J/ψ→μ⁻μ⁺衰变的末态中测量b重子的质量。我们发现：B⁺质量m(B⁺)=5279.10±0.41（统计）±0.36（系统）MeV/c²，B⁰质量m(B⁰)=5279.63±0.53（统计）±0.33（系统）MeV/c²，Bₛ⁰质量m(Bₛ⁰)=5366.01±0.73（统计）±0.33（系统）MeV/c²，Λb⁰质量m(Λb⁰)=5619.7±1.2（统计）±1.2（系统）MeV/c²。m(B⁺)-m(B⁰)=-0.53±0.67（统计）±0.14（系统）MeV/c²，m(Bₛ⁰)-m(B⁰)=86.38±0.90（统计）±0.06（系统）MeV/c²，m(Λb⁰)-m(B⁰)=339.2±1.4（统计）±0.1（系统）MeV/c²。Bₛ⁰、Λb⁰质量以及m(Bₛ⁰)-m(B⁰)和m(Λb⁰)-m(B⁰)质量差的测量精度优于当前世界平均值。
