“…We confirm the result of Czarnecki et al. for the bosonic part and present the complete sin^2 \theta_W dependence of the fermionic contribution. The approach is then used to compute the leading-logarithm three-loop electroweak contribution to a_mu. …”

“…Several models predict the existence of new gauge bosons leading to final states with high pT leptons: heavier copies of Standard Model W and Z, decaying to dilepton or lepton with missing ET; bosons coupling to right-handed fermions, as in Left-Right symmetric models, where the decay of a heavy neutrino leads to final states with leptons and jets. …”

“…If a Higgs-like particle is discovered, it is important to determine that it is the Higgs Boson of the Standard Model.In order to establish this, the parameters of the Higgs Boson itself and of the Higgs Mechanism shall be experimentally addressed, most notably its mass, charge, spin and parity as well as its relative and absolute couplings to fermions and bosons, i.e. its partial decay widths. …”

“…We look for events with three or more leptons, as well as direct searches for $WZ$ resonances, excited leptons and heavy fermions. The searches use data recorded in 2012 at $\sqrt{s}$=8\,TeV centre-of-mass energy by the ATLAS experiment at the LHC. …”

“…The production of a Higgs boson in association with a single top quark is one of a few channels which are sensitive for not yet excluded anomalous couplings of the Higgs boson to fermions. Multivariate analysis tools are used for the reconstruction and classification of signal events, where the Higgs boson decays into bottom quarks and the single top quark decays leptonically. …”

“…After the discovery of the Higgs boson, the ATLAS and CMS experiments have performed combined measurements of the mass of the Higgs boson and also measurements of the production and decay rates, as well as constraints on its couplings to vector bosons and fermions. These combined LHC measurements from the proton-proton collision Run-1 data will be summarized. …”

“…Higgs decay to a muon pair is the most promising way to probe Yukawa couplings to the second generation fermions at the LHC. Experimentally the analysis is challenging due to a small branching ratio (2.2*10^-4) and proceeds as a search for an excess at the Higgs mass in the dimuon invariant mass spectrum dominated by the irreducible Drell-Yan background. …”
