Next-to-Leading Order Evolution of Polarized Fragmentation Functions

چکیده
We present a brief description of the determination of the two-loop spindependent time-like splitting functions relevant for the NLO evolution of polarized fragmentation functions. Our calculation based on the analytic continuation of the corresponding space-like results obtained within the light-cone gauge method proposed by Curci, Furmanski, and Petronzio. As an application we present an analysis of polarized Λ production in ee and ep collisions.

Next-to-Leading Order Evolution of Polarized and Unpolarized Fragmentation Functions
We determine the two-loop ’time-like’ Altarelli-Parisi splitting functions, appearing in the next-to-leading order Q-evolution equations for fragmentation functions, via analytic continuation of the corresponding ’space-like’ splitting functions for the evolution of parton distributions. We do this for the case of unpolarized fragmentation functions and for the first time also for the functions...
متن کاملNext-to-leading order QCD evolution of transversity fragmentation functions
We derive the next-to-leading order splitting kernels for the scale evolution of fragmentation functions for transversely polarized quarks into transversely polarized hadrons. Very little is known so far about spin effects in fragmentation of partons into hadrons. An exception is semi-inclusive production of Λ baryons in e+e−, ep, or pp scattering, where the polarization of the Λ has been obser...

We calculate next to leading order QCD corrections to semi-inclusive polarized deep inelastic scattering and e + e − annihilation cross sections for processes where the polarization of the identified final-state hadron can also be determined. Using dimensional regularization and the HVBM prescription for the γ 5 matrix, we compute corrections for different spin-dependent observables, both in th...
متن کاملVirtual photon fragmentation functions
We introduce operator definitions for virtual photon fragmentation functions, which are needed for reliable calculations of Drell-Yan transverse momentum (QT ) distributions when QT is much larger than the invariant mass Q. We derive the evolution equations for these fragmentation functions. We calculate the leading order evolution kernels for partons to fragment into a unpolarized as well as a...
متن کاملA Study of Heavy Flavoured Meson Fragmentation Functions in e+e− annihilation
We compare QCD theoretical predictions for heavy flavoured mesons fragmentation spectra in e+e− annihilation with data from CLEO, BELLE and LEP. We include several effects in our calculation: nextto-leading order initial conditions, evolution and coefficient functions. Soft-gluon effects are resummed at next-to-leading-log accuracy. A matching condition for the crossing of the bottom threshold ...
