Measurement of neutral current Drell-Yan production at 8 TeV with the ATLAS detector
TL;DR: In this paper, a measurement of the forward-backward asymmetry AFB was obtained from the differential cross-section by summing over the cos θ∗ > 0 (forward) and the cos ∗ < 0 (backward) events and taking their difference.

Higgs production in association with top quarks at the LHC
TL;DR: In this article, the suitability of MadGraph for the generation of tb¯¯b events is explored, with a view to simulating this background, in searches for the Standard Model Higgs production and decay process.

NNLO soft function for top quark pair production at small transverse momentum
TL;DR: In this article, the soft function for top quark pair production at the next-to-next-to leading order is analyzed. But the soft functions are not the key ingredients that appear in the factorization formula, which mediates soft gluon exchanges between particles and gives rise to colour correlations.

TL;DR: In this article, a search for the production of a heavy B quark, having electric charge −1/3 and vector couplings to W, Z, and H bosons, is carried out using proton-proton collision data recorded at the CERN LHC by the CMS experiment, corresponding to an integrated luminosity of 19.7
An inclusive search for supersymmetry in 13 TeV proton-proton collision data
TL;DR: In this article, results are presented from a generic search for strongly produced supersymmetric particles in collisions in the multijet + missing-transverse momentum final state, and the results are interpreted as limits on simplified SUSY models.
