Associated production of a top-quark pair with vector bosons at NLO in QCD: impact on $t \bar{t} H$ searches at the LHC

TL;DR: In this article, the production of a top-quark pair in association with one and two vector bosons at the LHC was studied, and the authors provided predictions at next-to-leading order in QCD for total cross sections and topquark charge asymmetries as well as for differential distributions.

The Higgs Portal Above Threshold

TL;DR: In this article, the authors systematically explore the collider signatures of singlet scalars produced via the Higgs Portal at the 14 TeV LHC and a prospective 100 TeV hadron collider.

Postinflationary vacuum instability and Higgs-inflaton couplings

TL;DR: In this paper, the authors examined the Higgs dynamics during the preheating epoch, focusing on the effects of the parametric and tachyonic resonances, and provided an upper bound on quartic and trilinear interactions between Higgs and the inflaton.

Radiative generation of the Higgs potential

TL;DR: In this article, the authors considered the minimal extension of the Standard Model with U ( 1 ) B − L gauge symmetry for generating the Higgs potential radiatively and showed that there is a reasonable parameter space that is consistent with a correct electroweak symmetry breaking and the observed Higgs mass.

Search for charged Higgs bosons produced in association with a top quark and decaying via H± → τν using pp collision data recorded at √s=13 TeV by the ATLAS detector

Morad Aaboud, +2834 more
- 10 Aug 2016 - 
TL;DR: In this article, a statistical analysis leads to confidence-level upper limits on the production cross section times branching fraction, between 1.9 pb and 15 fb, for charged Higgs boson masses ranging from 200 to 2000 GeV.

PYTHIA 6.4 Physics and Manual

TL;DR: The Pythia program as mentioned in this paper can be used to generate high-energy-physics ''events'' (i.e. sets of outgoing particles produced in the interactions between two incoming particles).

The anti-$k_t$ jet clustering algorithm

TL;DR: The anti-k-t algorithm as mentioned in this paper behaves like an idealised cone algorithm, in that jets with only soft fragmentation are conical, active and passive areas are equal, the area anomalous dimensions are zero, the non-global logarithms are those of a rigid boundary and the Milan factor is universal.

A Brief Introduction to PYTHIA 8.1

TL;DR: PYTHIA 8 represents a complete rewrite in C++, and does not yet in every respect replace the old code, but does contain some new physics aspects that should make it an attractive option especially for LHC physics studies.
