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 present an overview of theoretical aspects of the phenomenon of gluon saturation in
high energy scattering in Quantum Chromo Dynamics. Then we review the state-of-the-art of …

The Review summarizes much of particle physics and cosmology. Using data from previous
editions, plus 2,143 new measurements from 709 papers, we list, evaluate, and average …

We present a new version of the hadron interaction event generator sibyll. While the core
ideas of the model have been preserved, the new version handles the production of baryon …

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 …

A bstract We present a new model for the hadronisation of multi-parton systems, in which
colour correlations beyond leading NC are allowed to influence the formation of confining …

Epos is a Monte Carlo event generator for minimum bias hadronic interactions, used for both
heavy ion interactions and cosmic ray air shower simulations. Since the last public release …

We present 9 new tunes of the p⊥-ordered shower and underlying-event model in Pythia
6.4. These “Perugia” tunes update and supersede the older “S0” family. The data sets used …

We describe the implementation details of the colour reconnection model in the event
generator Herwig++. We study the impact on final-state observables in detail and confirm the …
