Search for light pseudoscalar bosons, pair-produced in Higgs boson decays in the four-electron final state in proton-proton collisions at = 13 TeV
CMS Collaboration
A search for pairs of light neutral pseudoscalar bosons (A) resulting from the decay of a Higgs boson is performed. The search is conducted using LHC proton-proton collision data a…
First evidence for mixing-induced violation in B J/(1020) decays in pp collisions at 13 TeV
CMS Collaboration
A novel machine-learning-based flavor-tagging algorithm combining same-side and opposite-side tagging is used to obtain the equivalent of 27000 tagged B J/…
Combination and interpretation of differential Higgs boson production cross sections in proton-proton collisions at = 13 TeV
CMS Collaboration
Precision measurements of Higgs boson differential production cross sections are a key tool to probe the properties of the Higgs boson and test the standard model. New physics can…
Search for light pseudoscalar boson pairs produced from Higgs boson decays using the 4 and 22 final states in proton-proton collisions at = 13 TeV
CMS Collaboration
A search for a pair of light pseudoscalar bosons (a) produced in the decay of the 125 GeV Higgs boson is presented. The analysis examines decay modes where one a decays int…
Measurement of D meson photoproduction in ultraperipheral heavy ion collisions
CMS Collaboration
This Letter reports the first measurement of photonuclear D meson production in ultraperipheral heavy ion collisions. The study is performed using lead-lead collision data, wit…
Observation of suppressed charged-particle production in ultrarelativistic oxygen-oxygen collisions
CMS Collaboration
A hot and dense state of nuclear matter, known as the quark-gluon plasma, is created in collisions of ultrarelativistic heavy nuclei. Highly energetic quarks and gluons, collective…
