Abstract：
Taking into account the jet quenching,we calculate dihadron production numerically when a hard parton jet produced in relativistic high energy heavy ion collision passes through strong interaction medium.It turns out that the dihadron with large invariable mass spectrum and large transverse momentum are all suppressed in the central nucleus-nucleus collision because of jet quenching effect.It is similar to the p-p collision,the produced hadron back-to-back correlation is strong for the peripheral nucleus-nucleus collision.This correlation is much weaker with decreasing the values of compact parameter.
