We consider a rotating quark-antiquark (qqĖā) 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 and for fixed angular velocity as Ī»ā1 decreases
the string endpoints get more and more separated. To study R2
corrections, rotating quark-antiquark system in Gauss-Bonnet background has
been considered. We summarize the effects of these corrections in the
conclusion section.Comment: 21 pages, 11 figures, NPB version, corrections to the effects of
