Understand

The measurement of $B_s$-meson branching fractions is a fundamental tool to probe physics beyond the Standard Model.

Every measurement of untagged time-integrated $B_s$-meson branching fractions is model-dependent due to the time dependence of the experimental efficiency and the large lifetime difference between the two $B_s$ mass eigenstates.
In recent measurements, this effect is bundled in the systematics.
We reappraise the potential numerical impact of this effect -- we find it to be close to 10% in real-life examples where new physics is a correction to dominantly Standard-Model dynamics.
