We investigate a new structure for machine learning classifiers built with neural networks
and applied to problems in high-energy physics by expanding the inputs to include not only …

After the discovery of the top quark more than 20 years ago, its properties have been studied
in great detail both in production and in decay. Increasingly sophisticated experimental …

A bstract A search for new particles that decay into top quark pairs is reported. The search is
performed with the ATLAS experiment at the LHC using an integrated luminosity of 20.3 fb …

This report of the BOOST2012 workshop presents the results of four working groups that
studied key aspects of jet substructure. We discuss the potential of first-principle QCD …

A bstract We consider dark sector particles (DSPs) that obtain sizeable interactions with
Standard Model fermions from a new mediator. While these particles can avoid observation …

A search is performed for the production of heavy resonances decaying into top-antitop
quark pairs in proton-proton collisions at s= 8 TeV. Data used for the analyses were …

A search for a heavy resonance decaying into a top quark and antiquark ($\mathrm {t\bar {t}}
$) pair is performed using proton-proton collisions at $\sqrt {s}= $13 TeV. The search uses …

A bstract One of the main implications of the LHC discovery of a Higgs boson with a mass M
h≈ 126 GeV is that the scale of supersymmetry-breaking in the Minimal Supersymmetric …

A search for new particles that decay into top quark pairs (tt¯) is performed with the ATLAS
experiment at the LHC using an integrated luminosity of 4.7 fb-1 of proton–proton (pp) …

Weak corrections for top-quark pair production at hadron colliders are revisited. Predictions
for collider energies of 8 TeV, adopted to the recent LHC run, and for 13 as well as 14 TeV …
