The most recent LHC data have provided a considerable improvement in the precision with which various Higgs production and decay channels been measured. Using all available public results from ATLAS, CMS Tevatron, we derive for each final state combined confidence level contours signal strengths ($\mathrm{\text{gluon fusion}}+\mathrm{\text{top-quark}}$ pair associated production) versus ($\mathrm{\text{vector boson fusion}}+$ vector bosons) space. These ``combined strength ellipses'' can be...
We present the implementation, in MadAnalysis 5 framework, of several ATLAS and CMS searches for supersymmetry data recorded during first run LHC. provide extensive details on validation our implementations propose to create a public analysis database within this framework.
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at weak scale. When produced experiments such as Large Hadron Collider (LHC) CERN, these long-lived (LLPs) decay far from interaction vertex of primary proton-proton collision. Such LLP signatures distinct those promptly decaying targeted by majority searches for new physics LHC, often requiring customized techniques identify, example, significantly displaced vertices, tracks with...
First-principle simulations are at the heart of high-energy physics research program. They link vast data output multi-purpose detectors with fundamental theory predictions and interpretation. This review illustrates a wide range applications modern machine learning to event generation simulation-based inference, including conceptional developments driven by specific requirements particle physics. New ideas tools developed interface will improve speed precision forward simulations, handle...
In the alignment limit of a multi-doublet Higgs sector, one mass eigenstates aligns with direction scalar field vacuum expectation values, and its couplings approach those Standard Model (SM) boson. We consider CP-conserving Two-Higgs-Doublet Models (2HDMs) Type I II near in which lighter two CP-even bosons, $h$, is SM-like state observed at 125 GeV. particular, we focus on 2HDM parameter regime where coupling $h$ to gauge bosons approaches that SM. review theoretical structure analyze...

We assess the extent to which various constrained versions of NMSSM are able describe recent hints a Higgs signal at LHC corresponding mass in range 123-128 GeV.
We present a general procedure to decompose Beyond the Standard Model (BSM) collider signatures presenting Z2 symmetry into Simplified Spectrum (SMS) topologies. Our method provides way cast BSM predictions for LHC in model independent framework, which can be directly confronted with relevant experimental constraints. concrete implementation currently focusses on supersymmetry searches missing energy, large variety of SMS results from ATLAS and CMS are available. As show-case examples we...
Searches in final states with two leptons plus missing transverse energy, targeting supersymmetric particles or invisible decays of the Higgs boson, were performed during Run 1 LHC. Recasting results these analyses context inert doublet model (IDM) using MadAnalysis 5, we show that they provide constraints on scalars significantly extend previous limits from LEP. Moreover, LHC allow us to test IDM limit very small Higgs--inert scalar coupling, where direct detection dark matter and width vanish.
To what extent is the 125.5 GeV Higgs-like resonance observed at LHC, compatible with Two-Higgs-Doublet-Models (2HDMs) - one of simplest extensions Higgs sector? The paper provides an exhaustive analysis.
The statistical models used to derive the results of experimental analyses are incredible scientific value and essential information for analysis preservation reuse. In this paper, we make case systematically publishing full discuss technical developments that practical.
