Search for the production of four top quarks in the single-lepton and opposite-sign dilepton final states in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2019)
A search for the standard model production of four top quarks (pp → t t ¯ t t ¯) is reported using single-lepton plus jets and opposite-sign dilepton plus jets signatures. Proton-proton collisions are recorded with the CMS ...
Search for supersymmetry in final states with photons and missing transverse momentum in proton-proton collisions at 13 TeV
(Journal of High Energy Physics, 2019)
Results are reported of a search for supersymmetry in final states with photons and missing transverse momentum in proton-proton collisions at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb−1 ...
Search for high mass dijet resonances with a new background prediction method in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
A search for narrow and broad resonances with masses greater than 1.8 TeV decaying to a pair of jets is presented. The search uses proton-proton collision data at s = 13 TeV collected at the LHC, corresponding to an ...
Measurement of properties of Bs0 → μ+μ− decays and search for B0 → μ+μ− with the CMS experiment
(Journal of High Energy Physics, 2020)
Results are reported for the Bs0→ μ+μ− branching fraction and effective lifetime and from a search for the decay B0→ μ+μ−. The analysis uses a data sample of proton-proton collisions accumulated by the CMS experiment in ...
Search for lepton flavour violating decays of a neutral heavy Higgs boson to μτ and eτ in proton-proton collisions at √s = 13 TeV

A search for lepton flavour violating decays of a neutral non-standard-model Higgs boson in the μτ and eτ decay modes is presented. The search is based on proton-proton collisions at a center of mass energy s = 13 TeV ...
Search for decays of the 125 GeV Higgs boson into a Z boson and a ρ or ϕ meson
(Journal of High Energy Physics, 2020)
Decays of the 125 GeV Higgs boson into a Z boson and a ρ0(770) or ϕ(1020) meson are searched for using proton-proton collision data collected by the CMS experiment at the LHC at s $$ \sqrt{s} $$ = 13 TeV. The ...
Search for dark photons in decays of Higgs bosons produced in association with Z bosons in proton-proton collisions at √s = 13 TeV
(Journal of High Energy Physics, 2019)
A search is presented for a Higgs boson that is produced in association with a Z boson and that decays to an undetected particle together with an isolated photon. The search is performed by the CMS Collaboration at the ...
Measurement of the top quark pair production cross section in dilepton final states containing one τ lepton in pp collisions at √s = 13 TeV
(Journal of High Energy Physics, 2020)
The cross section of top quark pair production is measured in the tt¯→(ℓνℓ)(τhντ)bb¯ final state, where τh refers to the hadronic decays of the τ lepton, and ℓ is either an electron or a muon. The data sample corresponds ...
Measurements of the pp -> WZ inclusive and differential production cross sections and constraints on charged anomalous triple gauge couplings at √s = 13 TeV

The WZ production cross section is measured in proton-proton collisions at a centre-of-mass energy s = 13 TeV using data collected with the CMS detector, corresponding to an integrated luminosity of 35.9 fb -1 . The inclusive ...
Investigation into the event-activity dependence of ϒ(nS) relative production in proton-proton collisions at s= 7 TeV
(Journal of High Energy Physics, 2020)
The ratios of the production cross sections between the excited ϒ(2S) and ϒ(3S) mesons and the ϒ(1S) ground state, detected via their decay into two muons, are studied as a function of the number of charged particles in ...
