TL;DR: In this article, the authors reported the observation of Higgs boson decays to $WW^{\ast}$ based on an excess over background of 6.1 standard deviations, where the Standard Model expectation is 5.8 standard deviations.

TL;DR: In this article, the authors explore the room for possible deviations from the Standard Model (SM) Higgs boson coupling structure in a systematic study of Higgs coupling scale factor benchmark scenarios using the latest signal rate measurements from the Tevatron and LHC experiments.

TL;DR: In this paper, experimental selection cuts can be used to exclude this region in search channels where the Higgs invariant mass cannot be reconstructed, where also sizable Higgs-continuum interference occurs.

TL;DR: In this article, the MadAnalysis 5 framework was used to implement several ATLAS and CMS searches for supersymmetry in data recorded during the first run of the first HPCA.

TL;DR: In this article, the authors search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in root s=8 TeV pp collisions with the ATLAS detector.

TL;DR: The Gelfant 4 toolkit as discussed by the authors is a toolkit for simulating the passage of particles through matter, including a complete range of functionality including tracking, geometry, physics models and hits.

TL;DR: The Pythia program as mentioned in this paper can be used to generate high-energy-physics ''events'' (i.e. sets of outgoing particles produced in the interactions between two incoming particles).

TL;DR: The anti-k-t algorithm as mentioned in this paper behaves like an idealised cone algorithm, in that jets with only soft fragmentation are conical, active and passive areas are equal, the area anomalous dimensions are zero, the non-global logarithms are those of a rigid boundary and the Milan factor is universal.

TL;DR: PYTHIA 8 represents a complete rewrite in C++, and does not yet in every respect replace the old code, but does contain some new physics aspects that should make it an attractive option especially for LHC physics studies.
