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 pert…
The dead cone effect in heavy quark jets observed in momentum space and its QCD explanation
Stefan Kluth, Wolfgang Ochs, Redamy Perez Ramos
The production of a heavy quark is accompanied by gluon bremsstrahlung with angular and momentum spectra predicted by perturbative Quantum Chromo Dynamics (QCD). The radiation off…
Dead cone effect in charm and bottom quark jets
Stefan Kluth, Wolfgang Ochs, Redamy Perez-Ramos
The evolution of a heavy quark initiated jet is mainly ruled by gluon bremsstrahlung. As a consequence of the dead-cone effect, this radiation is suppressed in the forward directio…
