Back-to-back jets: Fourier transform from b to kT

In an earlier paper, we derived an algorithm for calculating the cross section for e + +e − → A + B + X, with hadrons A and B nearly back to back. The result was given in transverse position ( b ) space for the Fourier transform of the small angle part of the cross section. Here we discuss the struc...

Description
Summary:In an earlier paper, we derived an algorithm for calculating the cross section for e + +e − → A + B + X, with hadrons A and B nearly back to back. The result was given in transverse position ( b ) space for the Fourier transform of the small angle part of the cross section. Here we discuss the structure of this result, particularly at large b, where purely perturbative calculations are not useful. We then describe how to return from b space to transverse momentum space.
