Infrared Safety in Factorized Hard Scattering Cross-Sections
The rules of soft-collinear effective theory can be used naı̈vely to write hard scattering cross-sections as convolutions of separate hard, jet, and soft functions. One condition required to guarantee the validity of such a factorization is the infrared safety of these functions in perturbation theory. Using e+e− angularity distributions as an example, we propose and illustrate an intuitive meth...
متن کاملSoft-gluon Corrections to Hard-scattering Cross Sections Through NNNLO
I present a systematic approach to calculating soft-gluon corrections through next-to-next-to-nextto-leading order for arbitrary hard-scattering cross sections. Using a unified approach, master formulas are derived for processes with both simple and complex color flows. Applications and numerical results are given for some processes of interest, including charged Higgs production and top quark ...
متن کاملDetermining the Factorizability of Hard Scattering Cross-Sections
The rules of soft-collinear effective theory can be used naı̈vely to write hard scattering cross-sections as convolutions of separate hard, jet, and soft functions. We describe an intuitive method to determine, at a given order in perturbation theory, whether these functions are truly infrared safe or not and, thus, whether or not the cross-sections factorize. Using angularity distributions as a...
متن کاملResummation and power corrections for factorized cross sections‡
Threshold resummation for factorizable cross sections in hadron-hadron collisions has a number of applications and extensions. We discuss factorization scale dependence, resummation at nonleading power in the moment variable, and the implications of resummation for power corrections in the hard momentum scale. ‡ Talk presented at the “International Europhysics Conference on High Energy Physics”...
متن کاملExchange Cross Sections for Hard Binaries
We present results on the exchange cross section for the interaction between a hard binary and a field of single stars, for arbitrary masses. The results are based partly on extensive numerical scattering experiments, and partly on analytic estimates of the mass-dependence of the cross section. They can be used to estimate the rate of exchange in an arbitrary mixture of masses, provided that th...
