With increasing instantaneous luminosity at the LHC come additional reconstruction
challenges. At high luminosity, many collisions occur simultaneously within one proton …

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 …

At the start of Run 2 in 2015, the LHC delivered proton-proton collisions at a center-of-mass
energy of 13 TeV. During Run 2 (years 2015-2018) the LHC eventually reached a luminosity …

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 …

Measurements of production cross sections of WZ and same-sign WW boson pairs in
association with two jets in proton-proton collisions at s= 13 TeV at the LHC are reported …

At the CERN LHC, instantaneous luminosities of up to 1.5× 1034 cm− 2 s− 1 [1] are
sufficiently large for multiple proton-proton (pp) collisions to occur in the same time window …

A bstract A direct search for the standard model Higgs boson, H, produced in association
with a vector boson, V (W or Z), and decaying to a charm quark pair is presented. The search …

A bstract A search is presented for additional scalar (H) or pseudoscalar (A) Higgs bosons
decaying to a top quark pair in proton-proton collisions at a center-of-mass energy of 13 …

A bstract Results are reported for the\({\mathrm {B}} _ {\mathrm {s}}^ 0\)→ μ+ μ− branching
fraction and effective lifetime and from a search for the decay B 0→ μ+ μ−. The analysis uses …

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 …
