LHC EFT WG note: SMEFT predictions, event reweighting, and simulation Open
This note provides a comprehensive overview of tools for predicting observables in the Standard Model effective field theory (SMEFT) at both tree level and one loop using event generators. We evaluate three primary methodologies–event rewe…

Ad interim recommendations for the Higgs boson production cross sections at $\sqrt{s} = 13.6$ TeV Open
This note documents predictions for the inclusive production cross sections of the Standard Model Higgs boson at the Large Hadron Collider at a centre of mass energy of 13.6 TeV. The predictions here are based on simple extrapolations of p…

LHC EFT WG Note: SMEFT predictions, event reweighting, and simulation Open
This note gives an overview of the tools for predicting expectations in the Standard Model effective field theory (SMEFT) at the tree level and one loop available through event generators. Methods of event reweighting, the separate simulat…

Higgs Physics at the HL-LHC and HE-LHC Open
The discovery of the Higgs boson in 2012, by the ATLAS and CMS experiments, was a success achieved with only a percent of the entire dataset foreseen for the LHC. It opened a landscape of possibilities in the study of Higgs boson propertie…

Beyond the Standard Model Physics at the HL-LHC and HE-LHC Open
This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in the search for Beyond the Standard Model (BSM) physics, of…

Algorithmic improvements and calibration measurements for flavour tagging at the ATLAS experiment Open
The identification of jets containing bottom or charm hadrons is crucial to the LHC physics program.Top-quark decays proceed almost exclusively through a $b$-quark. The Standard Model Higgs boson decays predominantly to $b\\bar{b}$ pairs. …
Review of Standard Model Higgs results at the ATLAS experiment Open
The investigation of the mechanism of electroweak (EW) symmetry breaking has been one of the main goals of the ATLAS experiment [1] research program at the CERN Large Hadron Collider (LHC). In the Standard Model (SM) of particle physics, t…
Flavour tagging algorithms and performance at the ATLAS experiment Open
The identification of jets containing $b$-hadrons ($b$-tagging) is a fundamental ingredient in the physics program of the ATLAS experiment. This proceeding presents the main $b$-tagging algorithms strategy employed for the 2016 LHC run.

Optimisation of the ATLAS $b$-tagging performance for the 2016 LHC Run Open
The performance of the current ATLAS $b$-tagging algorithms optimized ahead of the start of the 2016 Run-2 data taking is reported in this poster. The algorithms used to identify jets containing $b$-hadrons are briefly described and the im…
