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 ...
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 ...
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 ...
Combination of Searches for Higgs Boson Pair Production in Proton-Proton Collisions at s =13 TeV
(Physical Review Letters, 2019)
This Letter describes a search for Higgs boson pair production using the combined results from four final states: bbγγ, bbττ, bbbb, and bbVV, where V represents a W or Z boson. The search is performed using data collected ...
Studies of Beauty Suppression via Nonprompt D0 Mesons in Pb-Pb Collisions at sNN =5.02 TeV
(Physical Review Letters, 2019)
The transverse momentum spectra of D0 mesons from b hadron decays are measured at midrapidity (|y|<1) in pp and Pb-Pb collisions at a nucleon-nucleon center of mass energy of 5.02 TeV with the CMS detector at the LHC. The ...
Improved Value for the Gamow-Teller Strength of the Sn100 Beta Decay
(Physical Review Letters, 2019)
A record number of Sn100 nuclei was detected and new isotopic species toward the proton dripline were discovered at the RIKEN Nishina Center. Decay spectroscopy was performed with the high-efficiency detector arrays WAS3ABi ...
