摘要：

CDF和D0实验完成了对费米实验室Tevatron对撞机上质心能量为$\sqrt{s} = 1.96$ TeV的$p \bar p$碰撞中收集的全部统计数据的分析。本文介绍了两个合作组在含重$b$-和$c$-夸克的强子性质方面的几个新结果。这些结果包括寻找稀有衰变$B^0, B^0_s \to μ^+ μ^-$（CDF），研究$B_s \to Jψϕ$衰变的CP不对称性（CDF，D_0），测量同号双μ子电荷不对称性（D_0），测量$D^0 \to K^+K^-$和$D^0 \to π^+π^-$衰变的CP不对称性（CDF），以及测量$B_s \to D_s^{(*)+} D_s^{(*)-}$分支分数（CDF）.这两个实验仍然期望在重口味的特性上产生更多的结果。

英文摘要：

The CDF and D0 experiments finalize the analysis of their full statistics collected in the $p \bar p$ collisions at a center-of-mass energy of $\sqrt{s} = 1.96$ TeV at the Fermilab Tevatron collider. This paper presents several new results on the properties of hadrons containing heavy $b$- and $c$-quarks obtained by both collaborations. These results include the search for the rare decays $B^0, B^0_s \to μ^+ μ^-$ (CDF), the study of CP asymmetry in $B_s \to Jψϕ$ decay (CDF, D0), the measurement of the like-sign dimuon charge asymmetry (D0), the measurement of CP asymmetry in $D^0 \to K^+K^-$ and $D^0 \to π^+π^-$ decays (CDF), and the new measurement of the $B_s \to D_s^{(*)+} D_s^{(*)-}$ branching fraction (CDF). Both experiments still expect to produce more results on the properties of heavy flavours.
