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” …

The top quark mass is one of the most intriguing parameters of the standard model (SM). Its
value indicates a Yukawa coupling close to unity, and the resulting strong ties to Higgs …

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 Evidence for Higgs boson decay to a pair of muons is presented. This result
combines searches in four exclusive categories targeting the production of the Higgs boson …

A bstract A search is presented for new particles produced at the LHC in proton-proton
collisions at\(\sqrt {s}\)= 13 TeV, using events with energetic jets and large missing …

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 …

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 …

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 …

The discovery of the Higgs boson in 2012, by the ATLAS and CMS experiments, was a
success achieved with only a percent of the entire dataset foreseen for the LHC. It opened a …

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 …
