چکیده
We propose a method to analyze infrared contributions to non-inclusive processes in QCD. We use the one-loop Sudakov form factor as a working example. Borrowing techniques from renormalization theory, we construct coun-terterms for the contributions from the soft and collinear regions, and we relate them to eikonal Wilson lines taken along non-lightlike directions.

Infrared divergences and non - lightlike eikonal lines in Sudakov processes
We propose a method to analyze infrared contributions to non-inclusive processes in QCD. We use the Sudakov form factor as a working example. Borrowing techniques from renormalization theory, we construct “counterterms” for the contributions from the soft and collinear regions, and we relate them to eikonal Wilson lines taken along non-lightlike directions. We illustrate the method with explici...
متن کاملTypeset Using Revt E X 1
The HQET/NRQCD Lagrangian is computed to order α/m3. The computation is performed using dimensional regularization to regulate the ultraviolet and infrared divergences. The results are consistent with reparametrization invariance to order 1/m3. Some subtleties in the matching conditions for NRQCD are discussed. Typeset using REVTEX 1

I briefly review three topics of recent interest concerning power corrections, renor-malons and Sudakov resummation: (a) 1/Q corrections to event shape observables in e + e − annihilation, (b) power corrections in Drell-Yan production and (c) facto-rial divergences that arise in resummation of large infrared (Sudakov) logarithms in moment or 'real' space.

متن کاملProduction of Energetic Dileptons with Small Invariant Masses from the Quark-gluon Plasma * Typeset Using Revt E X
The resummation technique of Braaten and Pisarski is used for a complete calculation of the ααs-contribution to the production rate of dileptons with energy E ≫ T and invariant mass M < ∼T from a quark-gluon plasma. In particular the cancellation of the infrared singularity by medium effects is discussed in detail. PACS numbers: 12.38.Mh, 25.30.Rw, 12.38.Cy Typeset using REVTEX Supported by BMB...
