Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

With increasing instantaneous luminosity at the LHC come additional reconstruction
challenges. At high luminosity, many collisions occur simultaneously within one proton …

This article documents the muon reconstruction and identification efficiency obtained by the
ATLAS experiment for 139 fb^-1 fb-1 of pp collision data at s= 13 s= 13 TeV collected …

Modern general-purpose detectors at high-energy colliders are based on the concept of
cylindrical detection layers, nested around the beam axis. Starting from the beam interaction …

Sherpa is a general-purpose Monte Carlo event generator for the simulation of particle
collisions in high-energy collider experiments. We summarize essential features and …

The performance is presented of the reconstruction and identification algorithms for
electrons and photons with the CMS experiment at the LHC. The reported results are based …

The success of the physics programme of the CMS experiment at the CERN LHC requires
the particles created in the LHC collisions to be reconstructed and identified as accurately as …

New sets of CMS underlying-event parameters (“tunes”) are presented for the pythia 8 event
generator. These tunes use the NNPDF3. 1 parton distribution functions (PDFs) at leading …

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 …
