Unified approach to jet processes in quantum chromodynamics

We have analyzed in the leading-logarithm approximation a closed set of equations, the solution of which describes correctly the processes e+ + e- → anything, e+h → e + anything, and e+ + e- → h + anything. This approach allows us to justify clearly the application of the renormalization group and the so-called factorization property. Since the technique is basically a skeleton expansion, it should be useful to give a unified description of all jet processes
