The ALICE experiment was proposed in 1993, to study strongly-interacting matter at extreme
energy densities and temperatures. This proposal entailed a comprehensive investigation of …

Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

This manual describes the Pythia event generator, the most recent version of an evolving
physics tool used to answer fundamental questions in particle physics. The program is most …

We provide an overview of the status of Monte-Carlo event generators for high-energy
particle physics. Guided by the experimental needs and requirements, we highlight areas of …

The accuracy of parton-shower simulations is often a limiting factor in the interpretation of
data from high-energy colliders. We present the first formulation of parton showers with …

This Report summarizes the proceedings of the 2019 Les Houches workshop on Physics at
TeV Colliders. Session 1 dealt with (I) new developments for high precision Standard Model …

A bstract The identification of boosted heavy particles such as top quarks or vector bosons is
one of the key problems arising in experimental studies at the Large Hadron Collider. In this …

We propose extensions of the anti-kt and Cambridge/Aachen hierarchical jet clustering
algorithms that are designed to retain the exact jet kinematics of these algorithms, while …

A bstract Standard dipole parton showers are known to yield incorrect subleading-colour
contributions to the leading (double) logarithmic terms for a variety of observables. In this …

A bstract We present a simple parton-shower model that replaces the explicit angular
ordering of the coherent branching formalism with a differentially accurate simulation of soft …
