TL;DR: In this article, a lower bound of 114.4 GeV/c2 is established, at the 95% confidence level, on the mass of the Standard Model Higgs boson.
Abstract: The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have collected a total of 2461 pb-1 of e+e- collision data at centre-of-mass energies between 189 and 209 GeV. The data are used to search for the Standard Model Higgs boson. The search results of the four collaborations are combined and examined in a likelihood test for their consistency with two hypotheses: the background hypothesis and the signal plus background hypothesis. The corresponding confidences have been computed as functions of the hypothetical Higgs boson mass. A lower bound of 114.4 GeV/c2 is established, at the 95% confidence level, on the mass of the Standard Model Higgs boson. The LEP data are also used to set upper bounds on the HZZ coupling for various assumptions concerning the decay of the Higgs boson.

TL;DR: In this paper, the authors focused on the mechanism of electroweak symmetry breaking and the fundamental properties of the Higgs particle of the Standard Model and its decay modes and production mechanisms at hadron colliders and at future lepton colliders.

TL;DR: The results of the searches for the Higgs boson made by the 4 LEP experiments in data between 161 and 172GeV are presented in this paper, which gives an improved mass limit of 77GeV/c2.
