Drag force of moving quark at $$\mathcal N=2$$ supergravity. (English) Zbl 1329.83198
Summary: We consider a moving quark in the thermal plasma of the $${\mathcal N}=2$$ supergravity theory. By using the AdS/CFT correspondence we obtain energy loss of the quark. Then we consider the higher-derivative corrections in a charged AdS black hole and calculate the drag force on the moving quark in the thermal plasma. Also, we find a limit which $${\mathcal N}=2$$ supergravity solutions correspond to the $${\mathcal N}=4$$ super Yang-Mills solutions for the heavy quark.
