The Dead Cone Effect in Heavy-Quark Jets: A Unified Study from Charm and Bottom to Top
Redamy Perez-Ramos, Stefan Kluth, Wolfgang Ochs
We present a unified overview of recent progress in the study of QCD radiation in heavy-quark jets, focusing on the dead-cone effect. Using precision data from LEP at $\sqrt{s}=91.…

How to identify the dead cone in the top-quark jet
Stefan Kluth, Wolfgang Ochs, Redamy Perez-Ramos
The gluon emission from an energetic heavy quark is suppressed in the forward direction below the angle for a quark of mass and energy according to per…
