摘要：

We calculate the leading order BFKL amplitude for the exclusive diffractive process gamma(L)*(Q(1)(2))gamma(L)*(Q(2)(2)) -> rho(0)(L)rho(0)(L) in the forward direction, which can be studied in future high energy e(+)e(-) linear colliders. The resummation effects are very large compared to the fixed-order calculation. We also estimate the next-to-leading logarithmic corrections to the amplitude by using a specific resummation of higher order effects and find a substantial growth with energy, but smaller than in the leading logarithmic approximation.
