Description
While large logarithms arising from the IR structure of QCD can be
resummed to higher logarithmic accuracy for specific observables,
numerical calculations based on parton showers are formally correct to
LL only. However, they incorporate additional effects like local
momentum conservation, which are beyond this formal accuracy. As a
first step towards a quantitative study of these effects, a final
state parton shower is constructed which implements the exact NLL
result for certain observables. It is then used to obtain a detailed
comparison of the numerical size of approximations made in analytic
NLL calculations.
