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 …

A search for the pair production of first-generation scalar leptoquarks is performed using
proton-proton collision data recorded at 13 TeV center-of-mass energy with the CMS …

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 …

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 …

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 bstract Measurements of Higgs boson production cross sections and couplings in events
where the Higgs boson decays into a pair of photons are reported. Events are selected from …

Tau leptons play a crucial role in determining the nature of the 125GeV Higgs boson [1–5],
in searching for additional Higgs bosons [6–13], and in searching for other new particles [14 …

A search for the nonresonant production of Higgs boson pairs (HH) via gluon-gluon and
vector boson fusion processes in final states with two bottom quarks and two tau leptons is …

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 …

Since the discovery of the Higgs boson in 2012, detailed studies of its properties have been
ongoing. Besides its mass, its width—related to its lifetime—is an important parameter. One …
