IR - Renormalon Contribution to the Polarized Structure Function g 1
An estimation of the higher twist contribution to the polarized nonsinglet structure function g 1 is given. Its first moment is generally assumed to be small but this could be due to a cancellation of its contribution in different Bjorken-x ranges. We estimate the magnitude of g tw4 1 as a function of x in the framework of the renormalon method. The calculated higher-twist-correction to g 1 tur...
متن کاملIR - Renormalon Contribution to the Longitudinal Structure Function F L
The available data on F L suggest the existence of unexpected large higher twist contributions. We use the 1/N f expansion to analyze the renormalon contribution to the coefficient function of the longitudinal structure function F p−n L. The renormalon ambiguity is calculated for all moments of the structure function thus allowing to estimate the contribution of " genuine " twist-4 corrections ...
متن کاملRenormalon Contributions to Fragmentation Functions in Non Singlet Dis
This talk discusses the power behaved corrections to fragmentation functions for the current jet in non-singlet deep inelastic scattering. These corrections are estimated by means of a renormalon model using a dispersive approach 8. The assumption of a universal infrared finite coupling enables us to provide quantitative estimates.
متن کاملNakano : Planar Drawings of Plane Graphs 3 G 3 G 4 G 5 G 6 G 7 G 8 G 9 G 10 G
Given a plane graph G, we wish to nd a drawing of G in the plane such that the vertices of G are represented as grid points, and the edges are represented as straight-line segments between their endpoints without any edge-intersection. Such drawings are called planar straight-line drawings of G. An additional objective is to minimize the area of the rectangular grid in which G is drawn. In this...
متن کامل— G 5 and G 6 performance considerations
The CMOS-based IBM S/390 Parallel Enterprise Servers have always employed the technique of memory caching to bridge the gap between processor speed and mainmemory access time. However, that gap has widened with each succeeding system generation, requiring increasingly sophisticated, multiple-level cache structures in order to minimize memory-access latency. The IBM S/390 G5 and G6 include two-l...
