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.
