Inclusive Charged Hadron Production in Two-Photon Collisions at LEP
/ L3 Collaboration
Inclusive charged hadron production, $ m{e}^{+} m{e}^{-} ightarrow m{e}^{+} m{e}^{-}$ h$^{pm}$ X, is studied using 414 pb$^{-1}$ of data collected at LEP with the L3 detector at centre-of-mass energies between 189 and 202 GeV. Single particle inclusive differential cross sections are measured as a function of the particle transverse momentum, $p_t$, and pseudo-rapidity, $eta$. [...]

Measurement of W Polarisation at LEP
/ L3 Collaboration
The three different helicity states of W bosons produced in the reaction e+ e- -> W+ W- -> l nu q q~ at LEP are studied using leptonic and hadronic W decays. Data at centre-of-mass energies \sqrt s = 183-209 GeV are used to measure the polarisation of W bosons, and its dependence on the W boson production angle. [...]
