Search for the Standard Model Higgs Boson at LEP /DELPHI Collaboration ; ALEPH Collaboration ; L3 Collaboration ; OPAL Collaboration
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have collected 2461 pb−1 of e+e− collision data at centre-of-mass energies between 189 and 209 GeV, of which 536 pb−1 have energies above 206 GeV. The data have been used to search for the Standard Model Higgs boson. [...]

Prompt photon production in hadronic events at LEP / Boutigny, D (Annecy, LAPP)
We review some recent results on photon emission off quarks obtained by the four LEP experiments. These experimental results are compared to different Monte-Carlo predictions and to an exact matrix element calculation at the order (ems). [...]

LEP W measurements / Saeki, Takayuki (Tokyo U., ICEPP)
In June 1996, the LEP center-of-mass energy was raised to 161 GeV, just above the threshold of pair-production of W bosons, and LEP2 experiments started. [...]

LEP Higgs / Mori, T (Tokyo U., ICEPP)
LEP had long been the only place where the Higgs boson could be unambiguously searched for. As the LEP experiments verified the gauge interactions more and more rigorously, searches for the Higgs boson, which forms the very basis of the gauge theories, were taking on more and more importance in LEP physics. [...]

$l l \gamma \gamma$ events at LEP / Chang, Yuan-Hann (MIT)
The results of studies on the ef.7-y events with high 'Y'Y mass from the L3 experiment at LEP is reported. A clustering of events with 'Y'Y invariant mass around 60 GeV is observed. [...]

A measurement of the V-A x V-A structure of the weak charged current in semileptonic b decays and missing energy measurements / Behner, Frank (Zurich, ETH)
The polarization of the W-propagator in semileptonic b decays is measured with the 13 experiment at LEP via simultaneous observation of the charged lepton and the neutrino spectrum. The polarization is seen with more than 3 standard deviations and found to be in agreement with the V-AxV-A structure. [...]
