Determination of the spin and parity of all-charm tetraquarks
CMS Collaboration
The traditional quark model accounts for the existence of baryons, such as protons and neutrons, which consist of three quarks, as well as mesons, composed of a quark-antiquark pai…
Elliptic anisotropy measurement of the f(980) hadron in proton-lead collisions and evidence for its quark-antiquark composition
CMS Collaboration
Despite the f(980) hadron having been discovered half a century ago, the question about its quark content has not been settled: it might be an ordinary quark-antiquark ($\mathr…
Search for pair production of heavy particles decaying to a top quark and a gluon in the lepton+jets final state in proton-proton collisions at = 13 TeV
CMS Collaboration
A search is presented for the pair production of new heavy resonances, each decaying into a top quark (t) or antiquark and a gluon (g). The analysis uses data recorded with the CMS…
Measurement of multidifferential cross sections for dijet production in proton-proton collisions at = 13 TeV
CMS Collaboration
A measurement of the dijet production cross section is reported based on proton-proton collision data collected in 2016 at = 13 TeV by the CMS experiment at the CERN LHC…
The CMS statistical analysis and combination tool: COMBINE
CMS Collaboration
This paper describes the COMBINE software package used for statistical analyses by the CMS Collaboration. The package, originally designed to perform searches for a Higgs boson and…
Observation of the J/K decay
CMS Collaboration
Using proton-proton collision data corresponding to an integrated luminosity of 140 fb collected by the CMS experiment at = 13 TeV, the J/$Ï…
