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

$\Gamma _{{{\mathit B}_{{s}}^{0}} }$ and $\Delta \Gamma _{{{\mathit B}_{{s}}^{0}} }$ are the decay rate average and difference between two ${{\mathit B}_{{s}}^{0}}$ $\mathit CP$ eigenstates (light $−$ heavy).

"OUR EVALUATION" is provided by the Heavy Flavor Averaging Group (HFLAV, https://hflav.web.cern.ch/). It is derived from the averages of $\Gamma _{{{\mathit B}_{{s}}^{0}} }$ and $\Delta \Gamma _{{{\mathit B}_{{s}}^{0}} }$ (and their correlation).
