Journal ArticleDOI

Search for charged Higgs bosons through the violation of lepton universality in tt events using pp collision data at √S=7 TeV with the ATLAS experiment

Georges Aad, +2935 more
TL;DR: In this article, an analysis based on 4.6 fb(-1) of proton-proton collision data at root s = 7 TeV collected by the ATLAS experiment at the Large Hadron Collider is presented.
Journal ArticleDOI

Final results from DELPHI on the searches for SM and MSSM neutral Higgs bosons

Jalal Abdallah, +380 more
TL;DR: In this paper, the DELPHI searches for the Standard Model Higgs boson, together with benchmark scans of the Minimal Supersymmetric Standard Model (MSSM) neutral higgs bosons, used data taken at centre-of-mass energies between 200 and 209 GeV with a total integrated luminosity of 224 pb^-1.
Journal ArticleDOI

Production characteristics of K0 and light meson resonances in hadronic decays of the Z0

P. Abreu, +562 more
TL;DR: In this article, an analysis of K0 and the meson resonances K*±(892), ρ0(770), f0(975) and f2(1270) in hadronic decays of the Z0 is presented, based on about 973,000 multihadronic events collected by the DELPHI detector at LEP during 1991 and 1992.
Journal ArticleDOI

b-tagging in DELPHI at LEP

P. Abreu, +411 more
TL;DR: In this article, the standard method used for tagging b-hadrons in the DELPHI experiment at the CERN LEP Collider is discussed in detail and various discriminating variables used for the tagging and the procedure of their combination.
Journal ArticleDOI

Search for excited electrons and muons in √ s =8 TeV proton–proton collisions with the ATLAS detector

Georges Aad, +2960 more
TL;DR: In this article, an analysis of 13 fb−1 collisions at a centre-of-mass energy of 8 TeV was carried out at the ATLAS detector at the Large Hadron Collider, and a limit on the cross section times branching ratio as a function of the excited-lepton mass was established.
