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/…
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…
System-size dependence of charged-particle suppression in ultrarelativistic nucleus-nucleus collisions
CMS Collaboration
High-energy partons lose energy while propagating through the hot, strongly interacting medium produced in ultrarelativistic nucleus-nucleus collisions, leading to a suppression of…
Observation of nuclear modification of energy-energy correlators inside jets in heavy ion collisions
CMS Collaboration
Energy-energy correlators are constructed by averaging the number of charged particle pairs within jets, weighted by the product of their transverse momenta, as a function of the a…
