Abstract:  
We consider a rotating quarkantiquark (q―q) 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 Ushape string and angular velocity of rotating
meson. We also extend the results to the higher derivative
corrections i.e. ℜ^{2} and ℜ^{4} which correspond
to finite coupling corrections on the rotating quarkantiquark
system in the hot plasma. In ℜ^{4} case, the results are
similar to the case without correction, except that screening length will be smaller. To study ℜ^{2} corrections,
rotating quarkantiquark system in GaussBonnet background has been considered. In general effect of these corrections
