Fragmentation Functions ∗
We estimate the power corrections (infrared renormalon contributions) to the coefficient functions for the transverse, longitudinal and asymmetric fragmentation functions in e + e − annihilation, using a method based on the analysis of one-loop Feynman graphs containing a massive gluon. The leading corrections have the expected 1/Q 2 behaviour, but the gluonic coefficients of the longitudinal a...
متن کاملFragmentation Functions approach in pQCD fragmentation phenomena
Next-to-leading order parton fragmentation functions into light mesons are presented. They have been extracted from real and simulated ee data and used to predict inclusive single particle distributions at different machines. Talk given at the XXXI Rencontres de Moriond, QCD and hadronic interactions, Les Arcs, France March 24-31 1996

play a similarly fundamental role as those of the corresponding crossed ‘spacelike’ deep-inelastic scattering (DIS) process ep → eX . Their interpretation in terms of scale-dependent fragmentation functions D f (z,Q ), the ‘time-like’ counterparts of the parton distribution functions fH(x,Q ) of a hadron H , hence provides a further important, complementary test of perturbative QCD. Furthermore...
متن کاملSpin-dependent Fragmentation Functions
A confusing variety of new and exotic fragmentation functions (FFs) is discussed recently, in particular in the context of the extraction of the third, leading twist – hitherto unknown – nucleon distribution function. This transversity distribution h1(x) (frequently also denoted δq(x) or ∆Tq(x)) involves a flip of quark chirality, and therefore, requires a second chiral-odd function to form a c...
متن کاملT-odd fragmentation functions
We discuss the properties of fragmentation functions arising from the interference of two leading hadrons produced inside the same jet in the current fragmentation region of a hard process. For the case of semi-inclusive Deep Inelastic Scattering (DIS), a proper folding of the cross section, integrated over the azimuthal position of the detected hadrons, produces a factorized form that allows f...
