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…
Observation of coherent (1020) meson photoproduction in ultraperipheral PbPb collisions at = 5.36 TeV
CMS Collaboration
The first observation of coherent (1020) meson photoproduction off heavy nuclei is presented using ultraperipheral lead-lead collisions at a center-of-mass energy per nucleon p…
Search for new physics in jet multiplicity patterns of multilepton events at = 13 TeV
CMS Collaboration
A first search for beyond the standard model physics in jet multiplicity patterns of multilepton events is presented, using a data sample corresponding to an integrated luminosity…
Probing gluon fluctuations in nuclei with the first energy-dependent measurement of incoherent J/ photoproduction in ultraperipheral PbPb collisions
CMS Collaboration
Incoherent J/ photoproduction in heavy ion ultraperipheral collisions (UPCs) provides a sensitive probe of localized, fluctuating gluonic structures within heavy nuclei. This s…
