Search for a Higgs boson decaying into a Z and a photon in pp collisions at $s$ = 7 and 8 TeV

S. Chatrchyan, +2199 more
- 04 Nov 2013 - 
TL;DR: In this paper, a search for a Higgs boson decaying into a Z boson and a photon was performed using proton-proton collision datasets recorded by the CMS detector at the LHC.

New Production Mechanism for keV Sterile Neutrino Dark Matter by Decays of Frozen-In Scalars

TL;DR: In this paper, the existence of a scalar singlet particle which never entered thermal equilibrium in the early universe was considered, since it only couples to the Standard Model fields by a small Higgs portal interaction.

Automated event generation for loop-induced processes

TL;DR: In this article, the authors present the first fully automated implementation of cross-section computation and event generation for loop-induced processes, integrated in the MadGraph5_aMC@NLO framework.

On the Tuning and the Mass of the Composite Higgs

TL;DR: In this paper, the tuning of composite Higgs models with partial compositeness and its interplay with the predicted Higgs mass was analyzed quantitatively and three classes of models, characterized by different quantum numbers of the fermionic colored resonances associated with the top quark, the so-called top partners were identified.

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.
