Resummation and Power Corrections by Dressed Gluon Exponentiation
نویسنده
چکیده
Event-shape distributions in ee annihilation offer a unique laboratory for understanding perturbative and non-perturbative aspects of QCD. Dressed Gluon Exponentiation is a resummation method designed to evaluate differential cross sections close to a kinematic threshold and provide the basis for parametrization of power corrections. The method and its application in the case of the thrust and the heavy jet mass distributions in the two-jet region are briefly presented.

I discuss soft-gluon resummation and power corrections for event shape distributions, mostly in ee annihilation. I consider specifically the thrust, the C parameter, and the class of angularities, and show how factorization techniques and dressed gluon exponentiation lead to predictive models of power corrections that are firmly grounded in perturbative QCD. The scaling rule for the shape funct...
متن کاملRenormalon resummation and exponentiation of soft and collinear gluon radiation in the thrust distribution∗
The thrust distribution in e+e− annihilation is calculated exploiting its exponentiation property in the two-jet region t = 1 − T ≪ 1. We present a general method (DGE) to calculate a large class of logarithmically enhanced terms, using the dispersive approach in renormalon calculus. Dressed Gluon Exponentiation is based on the fact that the exponentiation kernel is associated primarily with a ...

متن کاملInclusive spectra in charmless semileptonic B decays by Dressed Gluon Exponentiation
The triple differential spectrum in B̄ −→ Xulν̄ is computed by Dressed Gluon Exponentiation (DGE). In this framework the on-shell calculation, converted into hadronic variables, can be directly used as an approximation to the meson decay spectrum, without involving a leading–power non-perturbative function. Sudakov resummation for the fully differential B̄ −→ Xulν̄ width is formulated in moment spa...
