The source radius is studied with low relative momentum $\\mathrm{p}--\\mathrm{p}$, $\\mathrm{\\overline{p}}--\\mathrm{\\overline{p}}$, $\\mathrm{p}--\\Lambda$ and $\\mathrm{\\overline{p}}--\\overline{\\Lambda}$ pairs as a function of the pair transverse mass $m_\\mathrm{T}$ considering for the first time in a quantitative way the effect of strong resonance decays. After correcting for this effect, the radii extracted for pairs of different particle species agree. This indicates that protons, antiprotons, \\Lambdas, and \\overline{\\Lambda}s originate from the same source. Within the measured $m_\\mathrm{T}$ range (1.1--2.2})~GeV/$c^2$ the invariant radius of this common source varies between 1.3 and 0.85 fm. These results provide a precise reference for studies of the strong hadron--hadron interactions and for the investigation of collective properties in small colliding systems.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.98857.v2/t1","@type":"Dataset","description":"Source radius $r_0$ as a function of\u3008$m_\\mathrm{T}$\u3009for the assumption of a purely Gaussian source.
