A particle consistent with the Higgs boson observed with the ATLAS detector at the Large Hadron Collider.

Measurements of the Properties of the Higgs Boson Using the Atlas Detector

In July 2012, the ATLAS [1] and CMS Collaborations announced the discovery of a new particle [2, 3] at the Large Hadron Collider (LHC) at CERN in the context of the search for the Higgs boson of the Standard Model of Particle Physics (SM). Since then, with an increased dataset, improved detector understanding and refined analysis strategies, a wide range of properties of this new particle has b...

Search for the Higgs boson in the diphoton decay channel with the ATLAS detector

These proceedings report on a search for the Standard Model Higgs boson in the diphoton decay channel in proton-proton collisions at center-of-mass energies of √ s = 7TeV and √ s = 8TeV using integrated luminosities of 4.8fb−1 and 5.9fb−1, respectively, recorded with the ATLAS detector at the Large Hadron Collider. The search is performed for Higgs boson masses between 110 and 150GeV. The expec...

Physikalisches Institut, Albert-Ludwig-Universität Freiburg, Hermann-Herder-Str. 3, D-79104 Freiburg Abstract.The Standard Model of elementary particles is remarkably succesful in describing experimental data. The Higgs mechanism as the origin of electroweak symmetry breaking and mass generation, however, has not yet been confirmed experimentally. The search for the Higgs boson is thus one of t...

Search for Higgs boson decays to a photon and a Z boson in pp collisions at √s=7 and 8 TeV with the ATLAS detector
