The data, collected in proton-proton collisions between 2011 and 2018, correspond to an integrated luminosity of 9 fb(-1). Evidence for a new structure in the J=psi p and J=psi(p) over bar systems with a mass of 4337(-4-2)(+7+2) MeV and a width of 29(-12-14)(+26+14) MeV is found, where the first uncertainty is statistical and the second systematic, with a significance in the range of 3.1 to 3.7 sigma, depending on the assigned J(P) hypothesis.", optnote="WOS:000759202300001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5157), last updated on Fri, 18 Mar 2022 10:11:36 +0000", issn="0031-9007", doi="10.1103/PhysRevLett.128.062001", opturl="https://arxiv.org/abs/2108.04720", opturl="https://doi.org/10.1103/PhysRevLett.128.062001", language="English" }
