High-energy cosmic rays are observed indirectly by detecting the extensive air showers
initiated in Earth's atmosphere. The interpretation of these observations relies on accurate …

We review the physics basis, main features and use of general-purpose Monte Carlo event
generators for the simulation of proton–proton collisions at the Large Hadron Collider …

The ratio of the B s 0 and B 0 fragmentation fractions, fs/fd, in proton-proton collisions at the
LHC, is obtained as a function of B-meson transverse momentum and collision center-of …

First released in 2010, the Rivet library forms an important repository for analysis code,
facilitating comparisons between measurements of the final state in particle collisions and …

The luminosity determination for the ATLAS detector at the LHC during pp collisions at s= s=
8 TeV in 2012 is presented. The evaluation of the luminosity scale is performed using …

The large rate of multiple simultaneous proton–proton interactions, or pile-up, generated by
the Large Hadron Collider in Run 1 required the development of many new techniques to …

The study of the internal structure of hadronic jets has become in recent years a very active
area of research in particle physics. Jet substructure techniques are increasingly used in …

This paper presents the method and performance of primary vertex reconstruction in proton–
proton collision data recorded by the ATLAS experiment during Run 1 of the LHC. The …

A new release of the Monte Carlo event generator Herwig (version 7.2) is now available.
This version introduces a number of improvements over the major version 7.0, notably: multi …

We present an updated set of parameters for the PYTHIA 8 event generator. We reevaluate
the constraints imposed by LEP and SLD on hadronization, in particular with regard to heavy …
