Abstract:
We consider a rotating quark-antiquark (qq) pair in N=4 thermal plasma. By using AdS/CFT correspondence, the properties of this system have been investigated. We study variation of rotating string radius at the boundary as a function of the tip of U-shape string and angular velocity of rotating meson. We also extend the results to the higher derivative corrections i.e. ℜ2 and ℜ4 which correspond to finite coupling corrections on the rotating quark-antiquark system in the hot plasma. In ℜ4 case, the results are similar to the case without correction, except that screening length will be smaller. To study ℜ2 corrections, rotating quark-antiquark system in Gauss-Bonnet background has been considered. In general effect of these corrections
