<!--In these units, the [[exponential decay|mean lifetime]] <math>\tau</math> of an unstable particle can be reexpressed in terms of its decay width <math>\Gamma</math> (in eV) via <math>\Gamma = \hbar/\tau</math>. For example, the [[List of mesons|B⁰ meson]] has a mean lifetime of 1,542(16) [[picosecond]]s, or a decay width of 4,269(44) x 10^-4 eV, and its mean decay length is <math>c\tau</math> = 462 <math>\mu</math>m.-->
