Connection between Distribution and Fragmentation Functions

We show that the quark fragmentation function $D(z)$ and the quark distribution function $q(x)$ are connected in the $z \to 1$ limit by the approximate relation $D(z)/z \simeq q(2-1/z)$, where both quantities are in their physical regions. Predictions for proton production in inelastic $e^+ e^-$ annihilation, based on the new relation and standard parametrizations of quark distribution functions, are found to be compatible with the data.

On the QCD Evolution of the Transversity Distribution

The QCD evolution of the transversity distributions is investigated and compared to that of the helicity distributions. It is shown that they differ largely in the small-$x$ region. It is also proved that the evolution preserves Soffer's inequality among the three leading-twist distribution functions.

Heavy quarks in charged-current deep inelastic scattering: a systematic phenomenological study

We present a systematic QCD analysis of the strange--charm and bottom--top contributions to transverse and longitudinal structure functions in charged--current deep inelastic scattering. Various ${\cal O}(α_s^1)$ schemes are studied and compared. The dependence of their predictions on the factorization scale $μ^2$ is investigated. The theoretical uncertainties resulting from the choice of the scheme and of $μ^2$ are estimated.
