Search for a Light Charged Higgs Boson Decaying to a W Boson and a CP -Odd Higgs Boson in Final States with eμμ or μμμ in Proton-Proton Collisions at s =13 TeV
(Physical Review Letters, 2019)
A search for a light charged Higgs boson (H+) decaying to a W boson and a CP-odd Higgs boson (A) in final states with eμμ or μμμ is performed using data from pp collisions at s=13 TeV, recorded by the CMS detector at the ...
Search for Physics beyond the Standard Model in Events with Overlapping Photons and Jets
(Physical Review Letters, 2019)
Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely ...
Observation of Single Top Quark Production in Association with a Z Boson in Proton-Proton Collisions at s =13 TeV
(Physical Review Letters, 2019)
The observation of single top quark production in association with a Z boson and a quark (tZq) is reported. Events from proton-proton collisions at a center-of-mass energy of 13 TeV containing three charged leptons (either ...
Measurement of the jet mass distribution and top quark mass in hadronic decays of boosted top quarks in pp collisions at √s = 13 TeV
(Physical Review Letters, 2020)
A measurement is reported of the jet mass distribution in hadronic decays of boosted top quarks produced in pp collisions at √s = 13 TeV. The data were collected with the CMS detector at the LHC and correspond to an ...
Jet Shapes of Isolated Photon-Tagged Jets in Pb-Pb and pp Collisions at sNN =5.02 TeV
(Physical Review Letters, 2019)
The modification of jet shapes in Pb-Pb collisions, relative to those in pp collisions, is studied for jets associated with an isolated photon. The data were collected with the CMS detector at the LHC at a nucleon-nucleon ...
Observation of the Production of Three Massive Gauge Bosons at s =13 TeV
(Physical Review Letters, 2020)
The first observation is reported of the combined production of three massive gauge bosons (VVV with V=W, Z) in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis is based on a data sample recorded ...
Observation of the Bs0→X(3872)ϕ Decay
(Physical Review Letters, 2020)
Using a data sample of proton-proton collisions at s=13 TeV, corresponding to an integrated luminosity of 140 fb−1 collected by the CMS experiment in 2016–2018, the Bs0→X(3872)ϕ decay is observed. Decays into J/ψπ+π− and ...
Search for W Boson Decays to Three Charged Pions
(Physical Review Letters, 2019)
For the first time, a search for the rare decay of the W boson to three charged pions has been performed. Proton-proton collision data recorded by the CMS experiment at a center-of-mass energy of 13 TeV, corresponding to ...
Search for Low-Mass Quark-Antiquark Resonances Produced in Association with a Photon at s=13 TeV
(Physical Review Letters, 2019)
A search for narrow low-mass resonances decaying to quark-antiquark pairs is presented. The search is based on proton-proton collision events collected at 13 TeV by the CMS detector at the CERN LHC. The data sample corresponds ...
Observation of Two Excited Bc+ States and Measurement of the Bc+ (2S) Mass in pp Collisions at s =13 TeV
(Physical Review Letters, 2019)
Signals consistent with the Bc+(2S) and Bc∗+(2S) states are observed in proton-proton collisions at s=13 TeV, in an event sample corresponding to an integrated luminosity of 143 fb-1, collected by the CMS experiment during ...
