H2.00001: Higgs results from ATLAS Invited Speaker: Gabriella Sciolla This presentation reviews the most recent measurements of the properties of the Higgs boson performed with the ATLAS detector at the Large Hadron Collider. After providing an overview of how the individual decay channels are reconstructed, we will focus on the techniques used to measure the mass, cross-sections, couplings, spin and parity of the newly discovered particle in order to shed some light on its nature.

H2.00002: Higgs Results from CMS Invited Speaker: Adolf Bornheim The Nobel Prize in physics 2013 has been awarded to Fran\c{c}ois Englert and Peter W. Higgs for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles which plays a crucial role in our understanding of electro-weak symmetry breaking. I will review the experimental results manifesting the discovery of the so called Higgs boson from the perspective of the Compact Muon Solenoid (CMS) collaboration. The review is based on the final results from the proton-proton collision data at 7 TeV and 8 TeV center-of-mass energy, collected in 2011 and 2012 in the initial run of the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN). Results on the properties of the new particle with a mass around 125 GeV, all in agreement with the expectations for the Standard Model (SM) Higgs boson, are highlighted. Latest results on the couplings between the Higgs and fermionic fields, in particular the final results of searches for a Higgs boson decaying into a b-quark or a tau-lepton pair, are presented. Non-SM Higgs searches are briefly summarized. Future perspectives for Higgs physics with CMS at LHC for the next data taking period starting in 2015 and beyond are discussed. [Preview Abstract] |

H2.00003: Precision calculations for Higgs Physics Invited Speaker: Ayres Freitas After the discovery of the Higgs boson at the LHC, the primary focus is now on the determination its couplings. Any deviation from the Standard Model predictions would indicate the presence of new physics. This talk will review the most relevant observables for this purpose, both from direct Higgs production at the LHC and from electroweak precision tests. For a reliable comparison between experiment and theory, higher-order radiative correction must be included in the computation of these observables. An overview of the most common calculational techniques will be given, in a form accessible to non-experts. Furthermore, I will summarize the current state of the art for the theoretical predictions of Higgs production at the LHC and electroweak precision observables within the Standard Model, and comment on the challenges that still need to be surmounted to keep theoretical uncertainties under control for the full LHC Higgs program.
