Search for Higgs boson pair production in the [Formula: see text] final state from pp collisions at [Formula: see text] TeVwith the ATLAS detector.

Georges Aad, +2824 more
TL;DR: In this paper, the decay products of each Higgs boson are reconstructed as a high-momentum system with either a pair of small-radius jets or a single large-radius jet, the latter exploiting jet substructure techniques and associated b-tagged track-jets.
Journal ArticleDOI

Search for strong production of supersymmetric particles in final states with missing transverse momentum and at least three b-jets at √s = 8 TeV proton-proton collisions with the ATLAS detector

Georges Aad, +2920 more
TL;DR: The results are interpreted in the context of several supersymmetric models involving gluinos and scalar top and bottom quarks, as well as a mSUGRA/CMSSM model, significantly extending the previous ATLAS limits.

Measurement of Spin Correlation in Top-Antitop Quark Events and Search for Top Squark Pair Production in pp Collisions at √s = 8 TeV Using the ATLAS Detector

Georges Aad, +2862 more
TL;DR: In this paper, a measurement of spin correlation in t (t) over bar production is presented using data collected with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a center of mass.

Constraints on the gluon PDF from top quark pair production at hadron colliders

TL;DR: In this article, the authors provide NNLO+NNLL theoretical predictions for top quark pair production based on all the available nNLO PDF sets, and compare them with the most precise LHC and Tevatron data.

Search for heavy neutral leptons in decays of W bosons produced in 13 TeV pp collisions using prompt and displaced signatures with the ATLAS detector

Georges Aad, +51 more
TL;DR: In this article, leptonic decays of W bosons extracted from 13 TeV proton-proton collisions at the LHC are used to search for heavy neutral leptons (HNLs) that are produced through mixing with muon or electron neutrinos.

Parton distributions for the LHC

The Three-loop splitting functions in QCD: The Singlet case

TL;DR: In this article, the authors compute the next-to-next-toleading order (NNLO) contributions to the three splitting functions governing the evolution of unpolarized non-singlet combinations of quark densities in perturbative QCD.

Top++: a program for the calculation of the top-pair cross-section at hadron colliders

TL;DR: The program Top++ calculates the cross-section in (a) fixed order approach with exact next-to-next-to leading order (NNLO) accuracy and (b) by including soft-gluon resummation for the hadronic cross- section in Mellin space with full next- to-next -to-leading logarithmic (NNLL) accuracy.
