B-tagging, leptons and missing energy in ATLAS after first data
The start-up of the Large Hadron Collider at CERN marks a new era in particle physics. This paper presents an overview of the ATLAS detector performance and first results extracted from data taken during the early LHC runs
Flavour-Independent Searches for Neutral Higgs Bosons decaying into hadrons with the DELPHI Detector at LEP2
Search for charged Higgs bosons: combined results using LEP data
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for pair-produced charged Higgs bosons in the framework of Two Higgs Doublet Models (2HDMs). The data of the four experiments have been statistically combined. The results are interpreted within the 2HDM for Type I and Type II benchmark scenarios. No statistically significant excess has been observed when compared to the Standard Model background prediction, and the combined LEP data exclude large regions of the model parameter space. Charged Higgs bosons with mass below 80 GeV/c2 (Type II scenario) or 72.5 GeV/c2 (Type I scenario, for pseudo-scalar masses above 12 GeV/c2 ) are excluded at the 95 % confidence level
