#### $\Gamma _{{{\mathit B}_{{s}}^{0}} }$

"OUR EVALUATION" is an average performed by the Heavy Flavor Averaging Group (HFLAV, https://hflav.web.cern.ch/) as described in our "Review on ${{\mathit B}}$ -${{\overline{\mathit B}}}$ Mixing" in the ${{\mathit B}^{0}}$ section of these Listings. It includes the measurements of $\Gamma _{{{\mathit B}_{{s}}^{0}} }$ and $\Delta \Gamma _{{{\mathit B}_{{s}}^{0}} }$ listed in this section, as well as constraints from effective lifetimes with pure $\mathit CP$ modes and flavor-specific modes.
