Description
The CMS collaboration presents direct measurement of the dead-cone effect in b-jets using $\sqrt{s}=13$ TeV proton-proton collision data. By applying iterative declustering to b-jets from dileptonic $t\bar{t}$ events, we uncover the angular distribution of soft emissions. The unfolded results demonstrate the suppression of collinear gluon radiation characteristic of the heavy-quark parton shower, confirming QCD predictions relative to light quarks.
