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 …

We review the theoretical and experimental progress in the Glauber model of multiple
nucleon and/or parton scatterings after the last 10–15 years of operation with proton and …

A bstract A search is presented for physics beyond the standard model (SM) using electron
or muon pairs with high invariant mass. A data set of proton-proton collisions collected by …

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 …

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 …

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 …

Results are presented from a search for new physics in high-mass diphoton events from
proton-proton collisions at $\sqrt {s} $= 13 TeV. The data set was collected in 2016-2018 …

The rate for Higgs (H) bosons production in association with either one (tH) or two ($\mathrm
{t\bar {t}} $ H) top quarks is measured in final states containing multiple electrons, muons, or …

We present a new version of the hadron interaction event generator sibyll. While the core
ideas of the model have been preserved, the new version handles the production of baryon …

A bstract Results are reported from a search for supersymmetric particles in the final state
with multiple jets and large missing transverse momentum. The search uses a sample of …
