QCD analysis of unpolarized and polarized Λ-baryon production in leading and next-to-leading order
QCD analysis of unpolarized and polarized Λ-baryon production in leading and next-to-leading order
We analyze experimental data for the production of \ensuremath{\Lambda} baryons in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation in terms of scale-dependent, QCD-evolved, \ensuremath{\Lambda} fragmentation functions. Apart from the vast majority of the data for which the polarization of an observed \ensuremath{\Lambda} was not determined, we also consider the recent CERN LEP measurements of the …
