"tau21 all" of "Measurement of jet substructure observables in $\mathrm{t\overline{t}}$ events from proton-proton collisions at $\sqrt{s} =$ 13TeV"

Distribution of $\tau_{21}$ reconstructed from all particles with pt > 1 GeV, unfolded to the particle level.

基于所有横向动量（transverse momentum）大于1 GeV的粒子重建得到的τ₂₁的分布，并已解卷至粒子层面。
