摘要：

Onium-onium scattering at high energy is used to illustrate a dipole picture of high energy hard scattering in the large N-c limit. Single and double BFKL, pomeron exchanges are calculated in the leading logarithmic approximation. An expression is given for the triple pomeron coupling when one of the pomerons' momenta is zero while the other two have momentum transfer, t. This expression is explicit and could be evaluated numerically. It has a (-t)(-1/2) singularity at t = 0.
