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” …

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 …

Abstract The Large Hadron Collider at CERN, delivering proton–proton collisions at much
higher energies and far higher luminosities than previous machines, has enabled a …

In LHC searches for new and rare phenomena the top-associated channel pp→ tt‾ W±+ X is
a challenging background that multilepton analyses must overcome. Motivated by sustained …

A bstract A search for a heavy Higgs boson in the mass range from 0.2 to 3.0 TeV, decaying
to a pair of W bosons, is presented. The analysis is based on proton-proton collisions …

This paper presents new sets of parameters (“tunes”) for the underlying-event model of the
herwig\, 7 HERWIG 7 event generator. These parameters control the description of multiple …

A bstract A measurement of the top quark mass is performed using a data sample enriched
with single top quark events produced in the t channel. The study is based on proton-proton …

A bstract A search for physics beyond the standard model in events with at least three
charged leptons (electrons or muons) is presented. The data sample corresponds to an …

The double differential cross sections of the Drell–Yan lepton pair (ℓ+ ℓ-, dielectron or
dimuon) production are measured as functions of the invariant mass m ℓ ℓ, transverse …

Özet The results of two searches for pair production of vectorlike T or B quarks in fully
hadronic final states are presented, using data from the CMS experiment at a center-of-mass …
