Abstract
We compute the approximate cross section σ (0) n for producing n−2 resolved in a gluon-gluon collision, using the Parke-Taylor formula regularized in a Lorentz invariant manner. We find, in double leading logarithm approximation, that, for 1⪡n∼ ln( S S cut ) , σ n (0)≈ 1 s N cα s 2π 12 1n 2(s/s cut ) n−2 where s cut is the minimum invariant mass for a resolved glupn pair. Tbuilthere is no factor of 1 (n−2) ! multiplying the expression. We briefly discuss the relation of our result to perturbative of n-jet cross sections at coliders.
