TL;DR: In this article, the results of a search for events containing at least one long-lived particle that decays at a significant distance from its production point into two leptons or into five or more charged particles are presented.

TL;DR: In this article, the authors present a general procedure to decompose Beyond the Standard Model (BSM) collider signatures presenting a $$\mathbb {Z}_2$$ symmetry into simplified model spectrum (SMS) topologies.

TL;DR: This work uses quantum and classical annealing (probabilistic techniques for approximating the global maximum or minimum of a given function) to solve a Higgs-signal-versus-background machine learning optimization problem, mapped to a problem of finding the ground state of a corresponding Ising spin model.

TL;DR: The discrepancy between the Standard Model theory and experimental measurement of the muon magnetic moment anomaly is connected to precision electroweak (EW) predictions via their common dependence on hadronic vacuum polarization effects as discussed by the authors.

TL;DR: In this paper, a search is performed for a massive vector-like quark T, with charge 2/3, that is pair produced together with its antiparticle in proton-proton collisions.

TL;DR: The Gelfant 4 toolkit as discussed by the authors is a toolkit for simulating the passage of particles through matter, including a complete range of functionality including tracking, geometry, physics models and hits.

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).

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.

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.
