Energy Loss of Heavy Quarks in a QGP with a Running Coupling Constant Approach

Pol B. Gossiaux, Joerg Aichelin

We show that the effective running coupling constant, ${\alpha }_{\mathrm{eff}}$, and the effective regulator, $\kappa {\tilde{m}}_D^2$, which we used recently to calculate the energy loss, $\frac{dE…
