This report reviews the study of open heavy-flavour and quarkonium production in high-
energy hadronic collisions, as tools to investigate fundamental aspects of Quantum …

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 …

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 observation of the production of four top quarks in proton-proton collisions is reported,
based on a data sample collected by the CMS experiment at a center-of-mass energy of 13 …

A bstract Three searches are presented for signatures of physics beyond the standard model
(SM) in ττ final states in proton-proton collisions at the LHC, using a data sample collected …

A new algorithm is presented to discriminate reconstructed hadronic decays of tau leptons
($\tau_\mathrm {h} $) that originate from genuine tau leptons in the CMS detector against …

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 …

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 …

At the CERN LHC [1], an efficient classification of hadronic decays of heavy standard-model
(SM) particles (objects) that are reconstructed within a single jet would provide a significant …

Measurements of differential and double-differential cross sections of top-quark pair (tt¯)
production are presented in the lepton+ jets channels with a single electron or muon and …
