Gluon radiation by heavy quarks at intermediate energies

Understand

Employing scalar QCD we study the gluon emission of heavy quarks created by the interaction with light quarks considered as dynamical scattering centers.

• We develop approximation formulas for the high energy limit and study when the full calculation reaches this high energy limit.
• For zero quark masses and in the high energy limit our model reproduces the Gunion-Bertsch results.
• We justify why scalar QCD represents a good approximation to the full QCD approach for the energy loss of heavy quarks.
