Search for new physics at LEP 2 / Gross, Eilam (Weizmann Inst.)
The results of the search for Higgs bosons, Charginos, Neutralinos, Sleptons, Squarks and light Gravitinos with the LEP accelerator at 130-172 GeV center-of-mass energy are briefly described. Prospects for Standard Model Higgs search at higher center-of-mass energies are also given..

Difermion Cross-sections At LEPII / Sachs, K (Freiburg U.)
Precision measurements at LEPII provide a unique test of Standard Model predictions. Re­sults from the four LEP collaborations ALEPH, DELPIII, L3 and OPAL on the difermion cross sections and asymmetries obtained at centre-of- mass energies between 192 and 202 GeV are presented. [...]

Measurement of the mass of the W boson at LEP and determination of electroweak parameters / Straessner, A (Aachen, Tech. Hochsch.)
Precise measurements of the W mass and width performed at LEP are presented, which yield $M_W$ = 80.427 ± 0.046 GeV and $Γ_W$ = 2.12 ± 0.11 GeV. A comparison is made between this direct determination and the W mass value obtained indirectly in an analysis of other electroweak measurements. [...]

Bose-Einstein correlations in W+ W- events at LEP2 / van Dalen, Jorn A (Nijmegen U.)
Analyses of Bose-Einstein Correlations in w+w- events at LEP2 by the four LEP collaborations are presented. In particular, Bose-Einstein correlations in w+w- overlap are investigated and the possible existence of these correlations between particles coming from different W's, which may influence the W mass measurements in the fully-hadronic channel e+e- --+ w+w- --+ qiihq3ij<.

2-fermion and 4-fermion production at LEP2 / van Vulpen, Ivo B (NIKHEF, Amsterdam)
We present the measurements on 2-fermion and 4-fermion production in e + e - collisions at centre-of-mass energies ranging from 192 to 202 Ge V as collected by the 4 LEP experiments in 1999. For processes with 2-fermions in the final state we present both production cross sections and asymmetries for event samples at low and high effective centre-of-mass energies, where the latter process is sensitive to possible contributions from various non-SM physics, like contact interactions or Z' exchange, and can therefore be used to set limits on parameters in those models [...]
