Search for H→γγ produced in association with top quarks and constraints on the Yukawa coupling between the top quark and the Higgs boson using data taken at 7 TeV and 8 TeV with the ATLAS detector

Georges Aad, +3099 more
- 05 Jan 2015 - 
TL;DR: In this article, a search is performed for Higgs bosons produced in association with top quarks using the diphoton decay mode of the Higgs Boson using the ATLAS detector at the CERN Large Hadron Collider, which corresponds to an integrated luminosity of 4.5 fb(-1) of proton-proton collisions at a center-of-mass energy of 7 TeV and 20.3 fb (-1) at 8 TeV.

How the huge energy of quantum vacuum gravitates to drive the slow accelerating expansion of the Universe

Qingdi Wang, +2 more
- 01 Mar 2017 - 
TL;DR: In this article, the authors investigate the gravitational property of the quantum vacuum by treating its large energy density predicted by quantum field theory seriously and assuming that it does gravitate to obey the equivalence principle of general relativity.

Cross-section measurements of the Higgs boson decaying into a pair of τ-leptons in proton-proton collisions at √s=13 TeV with the ATLAS detector

Morad Aaboud, +2928 more
- 10 Apr 2019 - 
TL;DR: In this article, a measurement of production cross sections of the Higgs boson in proton-proton collisions is presented in the H→ττ decay channel, and the analysis is performed using 36.1 fb-1 of data recorded by the ATLAS experiment at the Large Hadron Collider at a center of mass energy of s=13 TeV.

The anti-$k_t$ jet clustering algorithm

Matteo Cacciari, +2 more
- 16 Apr 2008 - 
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

Torbjörn Sjöstrand, +4 more
- 01 Jun 2008 - 
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.
