The study is based on an LHCb dataset recorded at centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5 fb$^{-1}$. The data disfavour a nonresonant $J/\\psi\\phi$ production but are consistent with a resonant model including several resonant states observed previously only in $B^+ \\to J/\\psi\\phi K^+$ decays. The $\\chi_{c0}(4500)$ state is observed with a significance over $5\\sigma$ and the $\\chi_{c1}(4274)$ is confirmed with a significance of more than $4\\sigma$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.153613.v1/t1","@type":"Dataset","description":"Total $J/\\psi(\\to \\mu^+ \\mu^-)\\phi(\\to K^+ K^-)$ diffractive production cross-section, multiplied by $\\mathcal{B}(J/\\psi \\to \\mu^+ \\mu^-)$ and $\\mathcal{B}(\\phi \\to K^+ K^-)$...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.153613.v1/t2","@type":"Dataset","description":"$\\chi_{c1}(4140) \\to J/\\psi(\\to \\mu^+ \\mu^-)\\phi(\\to K^+ K^-)$ diffractive production cross-section, multiplied by $\\mathcal{B}(J/\\psi \\to \\mu^+ \\mu^-)$ and $\\mathcal{B}(\\phi \\to K^+...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.153613.v1/t3","@type":"Dataset","description":"$\\chi_{c1}(4274) \\to J/\\psi(\\to \\mu^+ \\mu^-)\\phi(\\to K^+ K^-)$ diffractive production cross-section, multiplied by $\\mathcal{B}(J/\\psi \\to \\mu^+ \\mu^-)$ and $\\mathcal{B}(\\phi \\to K^+...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.153613.v1/t4","@type":"Dataset","description":"$\\chi_{c0}(4500) \\to J/\\psi(\\to \\mu^+ \\mu^-)\\phi(\\to K^+ K^-)$ diffractive production cross-section, multiplied by $\\mathcal{B}(J/\\psi \\to \\mu^+ \\mu^-)$ and $\\mathcal{B}(\\phi \\to K^+...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.153613.v1/t5","@type":"Dataset","description":"$\\chi_{c1}(4685) \\ \\mathrm{or} \\ \\chi_{c0}(4700) \\to J/\\psi(\\to \\mu^+ \\mu^-)\\phi(\\to K^+ K^-)$ diffractive production cross-section, multiplied by $\\mathcal{B}(J/\\psi \\to \\mu^+ \\mu^-)$...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.153613.v1/t6","@type":"Dataset","description":"Nonresonant $J/\\psi(\\to \\mu^+ \\mu^-)\\phi(\\to K^+ K^-)$ diffractive production cross-section, multiplied by $\\mathcal{B}(J/\\psi \\to \\mu^+ \\mu^-)$ and $\\mathcal{B}(\\phi \\to K^+ K^-)$...","name":"Table 6"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2809344?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/153613"}],"inLanguage":"en","name":"Observation of exotic $J/\\psi\\phi$ resonances in diffractive processes in proton-proton collisions","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2809344?version=1","version":1}
