Brazilian input to the European Strategy for Particle Physics Update
U. de Freitas Carneiro da Graça, G. Gil da Silveira, C. Jahnke +12
The Brazilian High-Energy Physics (HEP) community has expanded remarkably since its first involvement at CERN and Fermilab in the 1980s. Its recent organization under the Brazilian…
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…
