[Observation of the J/psi -> mu(+)mu(-)mu(+)mu(-) decay in proton-proton collisions at vs=13 TeV]

Agradecimentos: We congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort. In addition, we gratefully... Ver mais
Abstract: The J/psi -> mu(+)mu(-)mu(+)mu(-) decay has been observed with a statistical significance in excess of five standard deviations. The analysis is based on an event sample of proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the CMS experiment in 2018 and... Ver mais
