dc.descriptionThis paper presents recent time-dependent measurements of neutral B meson oscillations. Similar to the $K^0$--$\bar{K}^0$ system, there are two such systems involving the b quark: $B_d^0$--$\bar{B}_d^0$ and $B_s^0$--$\bar{B}_s^0$. Thus the physical states are respectively $K_{S}$ and $K_{L}$, $(B_d)_S$ and $(B_d)_L$, and $(B_s)_S$ and $(B_s)_L$. The oscillation between each pair of states can be used to determine their mass difference. The present world average for the $(B_d)_S$--$(B_d)_L$ mass difference is $Δm_d = 0.457\pm0.019 ps^{-1}$ (or $(3.01\pm0.13)\times 10^{-4}$ eV). Using $f_{B_s}$ = 12\% (the fraction of $B_s$ produced in b events), the current lower limit on the corresponding $Δm_s$ is 6.1 ps$^{-1}$ (or $4.0\times 10^{-3}$ eV).
