Description
The production of heavy-quark jets is accompanied by gluon bremsstrahlung. This radiation is suppressed at small angles and is proportional to the heavy-quark mass, a phenomenon known as the dead cone effect. In this talk, we present this effect for charm and bottom quark initiated jets using data from Z-boson decays in momentum space in the e+e− annihilation. The observed suppression is significantly stronger than that reported by the ALICE collaboration at the LHC. These findings will also be compared with preliminary results on the same effect in top-quark–initiated jets.
